You Gotta Have Blue Hair/Anime

""If you had any doubt about this being a Japanese cartoon, here is the official stamp, six merchicks with every inconceivable hair color you can imagine.""

- Review of the 70's anime adaptation of Hans Christian Andersen's The Little Mermaid on Retro Junk.

A list of anime and manga where you can find unnatural hair colours.

"Koto: Why not focus on something you're good at, Honey? Like dying your hair unnatural colors?"
 * At any rate, a list of anime not using this Trope would be shorter.
 * Urusei Yatsura has green-haired characters, though this is justified because they're aliens. The humans all seem to have natural hair colors.
 * In the color-pages of the manga, unlike in the anime, Lum's hair is actually rainbow-colored.
 * Subverted/deconstructed in Kemono no Souja Erin, as while Erin and her mother both have (impossibly) naturally green hair, other people notice, and it marks them as part of a village associated with black magic and general creepiness.
 * Chirico from Armored Trooper VOTOMS has blue hair, along with a few other minor characters. Most of the other major characters have normal hair colors, though.
 * Silvana Greone, Shaoli, and Chloe from Noir all have purple hair, albeit in different shades. Silvana's hair is light purple, Shaoli's is dark purple, and Chloe's is in between.
 * In addition to purple hair, each of these Femme Fatales has a suited alias as well. Silvana's dubbed "The Brutal Princess" or "The Intoccabile", Shaoli's nicknamed "The Cold Blooded Killer", and Chloe is aliased "The True Noir".
 * Dragon Ball has Bulma with blue hair. Trunks gets his purple hair from his grandfather and it turns gold when he's Super Saiyan.
 * In the manga, her hair is also purple, as well as Bra's. They could have also changed Trunks' for consistency, but noooo...
 * Also, in the anime, as opposed to the manga, Lunch (when not in her gun-toting form, where she's a blonde) doesn't have black hair with blue tones, but dark blue hair instead, almost like the print media example.
 * The opposite applies to Chichi, whose hair is regular black in the anime and blue-black in the manga. It seems like Akira Toriyama probably planned her to have, indeed, dark blue hair, but colored it black in the manga to save reticulum patterns (since her hair would be so dark it would be unnecessary), not the other way around.
 * Gundam Seed very carefully and deliberately averted this trope by giving unusual hair and eye colors ONLY to Coordinators, genetically engineered humans, while Naturals, those without genetic modification, had only natural hair and eye colors. The sequel, Gundam Seed Destiny, almost immediately screwed this up with Sting and Auel, Naturals with green and blue hair respectively.
 * Auel and Sting weren't the first Naturals to have unusual hair colours. Shani, one of the prototype Extended from Seed, had green hair. And there's nothing normal about he or Sting and Auel, what with their being drug-addicted Super Soldiers raised from birth to be living weapons. The only non-Coordinator, non-Extended to have an odd hair colour is Yuna Roma Seiran. And given some of his other, unusual style choices, that's hardly surprising.
 * Used as a plot point in the spinoff manga Gundam SEED Astray: the mercenary Kaite Madigan is a Coordinator whose parents abandoned him because, due to a genetic defect, his facial hair is a different color from the hair on his head.
 * Mobile Suit Gundam 00 seems to also have done this, where the only people with oddly colored hair (light/dark purple, pastel green, blue) are genetically-engineered Innovators, or experimentally modified Super Soldiers, making them easy to spot from a mile away. Having rather odd names (by Real Life standards) also does a good job of spotlighting them.
 * Feldt, a normal human, has bubble-gum pink hair, but it turns out she dyes it out of a complex from having been raised in space unlike other people.
 * Played completely straight in Gundam AGE. Besides Flit Asuno having green hair, there are countless hair colors ranging from normal colors like brown and grey to unusual colors like purple and crimson. Two characters, Ract, the leader of Euba, and Yark Dore, the Disc One Final Boss, even have two hair colors (blonde/red for Ract and blue/gold for Yark).
 * Sailor Moon has characters with huge amounts of weird hair colors.
 * In one of the manga side stories (and the anime special based on it), Chibi-Usa's new classmates actually point out that she has pink hair, which is apparently unusual from the characters' point of view. Makes one wonder if everyone else's hair colors are real, and if so, why nobody finds them odd. Is it only pink that is considered weird?
 * Pink is actually the closest to a real color you could get out of the series. Hasn't anyone ever heard of strawberry blonde?
 * In the Sailor Moon manga, Sailor Jupiter has curly auburn hair. In chapter five, when one of the teachers confronts her about it, she insists that it's natural.
 * The live-action version made their signature hair part of their costumes, which was the creator's original intention. She had wanted the girls to all have more natural hair colors that would then turn into the fantastical rainbow hairstyles when they transformed. It was supposed to add to the disguise as well as accentuate the magic involved in their transformations.
 * The funny thing about Zero no Tsukaima is that while everyone in Halkeginia has hair from some spectrum of the rainbow, no one except those of Japanese descent have black hair, like Saito and
 * The eponymous character of Yu-Gi-Oh!! has three-colored hair -- black, gold, and pink. Aside from that, the show tends more toward weird hair styles then weird hair colors -- indeed, some of the odder hair colours from Season 0 (such as Kaiba's bright radium-green hair) were recoloured to something more probable for the better known later seasons.
 * Though Kaiba's green hair is an Adaptation Dye Job. Whenever he shows up somewhere on the cover of the first 7 manga season 0 was loosely based on, he clearly has brown hair.
 * Bleach runs the entire range from natural hair types, to implausible hair types to impossible hair types.
 * Implausible hair types include Orihime (a orange-chestnut in the manga, orange in the anime) and Ichigo (the shade of orange that Asian hair turns when bleached). Both of them have been stigmatised in school because of their unusual hair colours. Blond examples include Harribel, Yuzu, Urahara, Rangiku, Kira, Kiyone, Yukio. Brunette examples include Aizen, Keigo, Sado, Starrk.
 * Blue hair: Grimmjow, Mayuri
 * Green hair: Nel, Mashiro
 * Pink hair: Szayel, Yachiru, Hacchi,
 * Purple hair: Yoruichi, Riruka
 * Red hair (impossible shades): Renji, Chizuru, Jinta
 * White Hair (that's not a result of age): Gin, Hitsugaya, Isane, Kensei, Ukitake (whose hair turned white as a young child due to his illness), Ryuuken Ishida (in the manga, his hair was white even in his youth, although the anime changes this to brown which would make him an example of an implausible hair type)
 * Naruto has Sakura, who has pink hair (and Theme Naming based upon her hair colour). And it's apparently natural, unless she's going to the trouble of dying her eyebrows. If not for her, it would fit possibly into plausible hair due to the show not being set in Japan (even though everyone is culturally Japanese). However, Konan in Akatsuki has blue/purple/periwinkle hair, and Pein has Orange hair.
 * Blond hair is quite common in the Naruto universe (Naruto himself, Ino, Temari, Kankuro, Temari's mother and uncle, Tsunade, Deidara, the 4th Hokage), as are gray-haired young people (Kakashi [whose Backstory puts him in his late twenties, Kabuto).
 * Many other character also have odd hair colors, such as Gaara, Sasori, and Kushina Uzumaki with red, Jiraiya with white (even as a kid), Zetsu and the only-seen-on-a-manga-cover seven tailed-host with green, Kisame Hoshigaki and Konan with dark blue, Suigetsu Hozuki, Sakon and Ukon, Kimimaro Kaguya, Hidan, everyone from the Cloud Village but Yugito (blonde), Karui (red), and the Head Ninja (black), the aforementioned Kakashi Hatake, and Kabuto Yakushi all with silver hair, and Juugo with orange hair.
 * On the cover of Volume 24, Sakon has purplish hair.
 * Madara mentions that Uzumakis (well, pure blooded ones anyway) all have red hair. Naruto's hair is blond because of his father, and
 * Sasuke's hair is black but, at times (especially in Part 1), his hair appears to be blue, probably to fit the rest of his clothes, but later on, his hair is black with blueish tints on it.
 * Tayuya's hair is red or dark pink depending on who you ask.
 * Before a certain manga cover was released, everyone assumed Karin's hair was black because of the completely solid black it was shown as in the regular pages, but it showed it was supposed to be bright red. Similarly,, Nagato seemed to have possibly black hair in the manga, but when colored, was shown to be blood red/crimson.
 * Kishimoto has done this, again, with the Mizukage, who looks blond (as in, left uncolored) in the manga but a new cover revealed her to have Chestnut Brownish Red hair.
 * Then her bodyguards, Ao and Chojuro, who had similarly uncolored hair in regular pages, was shown by a cover to have light blue hair. In fact, Kisame is apparently the same color (though you can't see his hair very often).
 * Hinata, aka the resident Shy Blue-Haired Girl.
 * The page picture comes from Mermaid Melody Pichi Pichi Pitch, where, for the mermaids at least (except for the Pink ones), hair color also indicates race. Humans and other characters (and Pink mermaids) can have any color.
 * Tokyo Mew Mew. Technically, at least Minto and Zakuro may have stylized black hair, and the anime version of Ichigo is a more or less plausible redhead, but then there are the obviously blonde Bu-ling and Ryou...Additionally, in the anime, the Mew Mews' hair colour changes from normal to outrageous when they transform, save for Zakuro and Retasu, whose hair remain purple and green (albeit different shades). In the manga, all five girls always have fancy hair colours, transformed or not.
 * Interestingly, in the manga, Zakuro is said to have black hair at one point, suggesting purple is, indeed, here just for convenience. Ryou Shirogane, on the other hand, is confirmed to have golden hair and blue eyes via the scene where Ichigo thinks he is the Blue Knight, citing said features as a similarity. Slightly odd, since this is the typical appearance of a "gaijin", which Ryou doesn't seem to be (he did live in America, but it is implied that his parents were Japanese).
 * Galaxy Angel, Galaxy Angel Rune, and Galaxy Angel gameverse.
 * Magic Knight Rayearth: Hikaru's hair is red and Umi's is blue. Various other odd hair colors pop up as well, but as Cephiro isn't Japan (or anywhere else on Earth), this is Justified.
 * In Ai Yori Aoshi, secondary characters have realistic hair coloring, but most of the lead characters don't. Kaoru's is brown (a very non-Japanese brown), Aoi's is (appropriately) blue, Taeko's is a reddish-brown, Miyabi's is a plum color, and Mayu's is bright purple.
 * Corrector Yui falls somewhere in between this and implausible. In the anime, Haruna has normal roan red hair, while Yui, being blonde, puts it at least at implausible. The other Correctors have rainbow hair, but they're computer programs. In the manga, though, Haruna has unmistakably purple hair, and in the second season of the anime, purple-haired Ai comes in from the real world.
 * I do, sir. I sure do. But changing the subject, in the anime, Ai's hair can pass as black, while in manga, it's dark purple (in the pilots, it's a greyish brown).
 * Yu Yu Hakusho's human characters have every possible natural hair color (except Genkai, who's graying now but originally had pink hair), while the more fantastic characters usually have more fantastic hair colors. Both Kurama and Kuwabara have red hair, for example, but they're very different shades.
 * To be fair, however, Genkai originally was strawberry-blonde.
 * Botan's is even lampshaded.


 * She still insists it's natural.
 * Kurama's hair is black (or dark blue) in the manga.
 * Mahou Sensei Negima has otherwise merely Improbable hair, until you get to Misa Kakizaki, the cheerleader with purple hair, and green-haired Ninja-girl Kaede. Not sure if Chachamaru, having light green hair, counts, as she's a Robot Girl. The animated adaptations, on the other hand, make it even worse, changing the hair colors of half the remaining cast.
 * In the manga, Kaede has sandy blonde hair, and Ayaka Yukihiro has golden blond hair.
 * Someone at one point says that Ayaka being good at English doesn't count, since she's only 'half', a claim which offends her and she denies.
 * Evangeline speculates in the manga that Setsuna probably has white hair and red eyes, but dyes her hair and wears contacts. We have never actually seen this in any of the different versions of the series, though.
 * Ako has bluish white hair, and Chisame has either green or bright orange hair, depending on if it's the anime or manga.
 * Samurai 7 has (mostly) plausible hair colors: browns and blacks. Then we get to redheaded Heihachi, blond Shichiroji and Kyuuzo, and Ukyo, who actually has blue hair.
 * Higurashi no Naku Koro ni falls victim to this. Keiichi and Tomitake's hair is brown, unusual for a full Japanese person, while Satoko, her immediate family, and Takano are all blonds (more unusual). Rena and Irie has orange hair (very unlikely for Rena, considering neither of her parents do), Rika and Chie have blue hair for no adequately explored reason, and the Sonozaki family women have green hair. Naturally, no one ever comments on any of this.
 * Rika's hair seems to change color after the first season (not entirely sure if it has to do with the lighting of the scene, or what). It looks like it switches from blue to aquamarine to purple throughout the series, as well as in artwork, figurines, etc.
 * In Umineko no Naku Koro ni, Rika's Expy Bernkastel's blue hair stands out when compared to the rest of the cast introduced up to that point, who had relatively reasonable hair colors, though it's justified since she is a magical being. It's blue in the visual novel sprites, but, in the anime, takes on a more purplish tint.
 * "Expy"? Not really.
 * Except Bernkastel states herself that
 * "Reasonable" would be a matter of perspective, given that the cast already had the very redheaded Battler and White-Haired Pretty Girl Kyrie. Possible in real life, but highly implausible on a Japanese teenager and his stepmom.
 * Actually, Rena's mom has red hair too.
 * In Suzumiya Haruhi, most characters hover around the brown-black-auburn spectrum; however, Ryoko, Emiri, Yuki, and Tsuruya have varying colors of green, blue, and grey.
 * In the anime and novel color pictures, Yuki's hair is purple.
 * However, nobody appears to find this strange. Could be that others do have strange hair or that their hair is actually just a visual cue for the audience to recognize these characters are not exactly normal. Perhaps, in 'reality', their hair color is something normal?
 * Outlaw Star falls somewhere between Impossible and Plausible hair colors. Most of the characters are white, and any characters of Asian ancestry have black or dark brown hair. On the other hand, we have Harry, who has blue-green hair, and Gene, whose hair is a shade of red that you're very unlikely to find in the real world.
 * Harry's hair is explainable: he's a bio-android like Melfina, a genetically engineered lifeform created using DNA samples taken from a dead human. And in a setting where that sort of thing is possible, and modifications of all sorts are quite common (so much so that neither Gene nor Jim is surprised when their bounty in the first episode is a cyborg, and Jim has to look up a specific model to figure out his vulnerable spot), if not cheap, then the possibility of DNA tweaking for aesthetic purposes comes up.
 * Cowboy Bebop has realistic-looking characters, so the vast majority of them fall under plausible hair colors...except for green-haired Spike, purple-haired Faye, and White-Haired Pretty Boy Vicious. No explanation given for these unusual hair colors and nobody notices.
 * As far as Spike and Faye, they're more than likely black-haired with highlights/contrast shades added in.
 * Almost no one has normal colored hair in Lucky Star. It's lampshaded when Miyuki (who has pink hair) explains to Konata (blue), Tsukasa, and Kagami (both purple) why exposure to sunlight and seawater changes hair color. Most, if not all, characters with funky hair colors also have that as their eye color. As such, one may pretend that their hair is perceived in their world as being black/dark brown.
 * This is completely ignored and lampshaded further in the dub, where Konata comments that Miyuki is like her mother "down to the last pink hair."
 * And, also in the dub, Misao (who actually has brown hair) calls Konata "Shorty McBlueHair" at one point when she asks if that's who wants to borrow the game Kagami is asking her to return.
 * Keroro Gunsou has Natsumi's pink hair, Momoka's (and her father's) light blue hair, and Saburou's silver hair for the human examples; the humanoid aliens seldom have "normal" hair colours. For the humans, though, this is implied to be the result of dye jobs.
 * Clark Kenting related example -- everyone in the world of Yes! Precure 5 has some shade of brown or black hair, except for the heroines, all of whom have hair in their respective hero colors even in civilian form. Red-haired Rin and (justified) blonde Urara might not stand out, but Nozomi, Komachi, and Karen's pink, blue, and green, coupled with the fact that the five spend a lot of time together...
 * Rin's got realistic-looking brown "red" hair, which becomes bright red when she transforms. So maybe that throws people off.
 * Saint Seiya has a lot of characters with impossible hair colors, most prominently Andromeda Shun, who has green hair. Shun's hair was normal light brown in the manga; it was changed for the animation to make him more noticeable.
 * In the manga, most of the Gold Saints have blonde hair, and the only exceptions are Dohko, who keeps his auburn hair from the anime, Deathmask, who has silver-grey hair in the manga, Camus, who has red hair, and Shura, who has black hair.
 * The blondes were eradicated in the anime (with the exception of Shaka) due to too much yellow when combined with the Gold Cloths. But a manga example would be Saga - his hair goes light purple at some points. Also, Shura's a brunette in the manga. As for the anime, a lot of hair get turned blue - Ikki, Deathmask, Aphrodite, Saga, Kanon, and Julian Solo got varying shades, Athena's hair turned lilac, Mu's became pink, Camus and Shura were given green hair, Milo's got turned purple, and Kiki went ginger. Miho got blue hair too. You can tell it's an 8Os anime!
 * Kenshin Himura from Rurouni Kenshin happens to have blood red hair.
 * The Revolutionary Girl Utena anime has Utena and Mikage (both pink), Anthy (purple), Akio, Mamiya, and Dios (all lilac), Touga (bright red), Saionji (green), Miki, Kozue, and Ruka (all blue), Juri (orange), and Shiori (wine, or perhaps raspberry). Everyone else's hair color is...possible, as most people have brown hair, some have black, and some (notably and implausibly Touga's sister, Nanami) are blonde.
 * Miki, Kozue, and Ruka all have different shades of blue hair (Ruka himself has two!), with Kanae's mother adding in yet another. Kanae herself, on the other hand, sometimes appears to have very bright green hair. Chigusa and the unnamed main character from the Sega Saturn game have cyan and magenta hair, respectively.
 * The hair color is so they'll be properly color coordinated.
 * Dirty Pair fall into this: Kei is a Dark-Skinned Redhead with an impossible shade of red hair, and Yuri's hair (even when it's referred to as black) is usually shown as blue. However, they are both genetically engineered transhumans with a questionable biology/cybernetics ratio.
 * Only two of the major characters in  Mai-HiME have anything resembling normal hair colors for a show set in Middle of Nowhere Town, Japan -- Yukino (brown) and Mikoto (black, with pigtails and Eyes of Gold). Naturally, there's also a blue-haired character in the mix, Miyu -- but, so she has an excuse.
 * Natsuki may also qualify as having "normal" hair -- it's dark blue in the anime, but the supplemental materials describe it as being black, so she most likely simply falls under "stylized black hair".
 * On the cover of the manga's second volume, Natsuki is shown with black hair.
 * Before the Pokémon anime changed to digital animation, James' hair was blue. Now, it's lavender (the dub has made a joke about this). Jessie's hair went from fire engine red to magenta and Tracy's was green even before the switch (just a darker shade, almost black).
 * Officer Jenny's hair changed from blue to blue-green.
 * Come on, Nurse Joy's hair is PINK! (All of them.)
 * Dawn has dark blue hair! That's what the page was named for!
 * And now we have Cilan, with bright green hair.
 * Iris' hair is purple. And huge, but that's a different trope.
 * Cyrus's hair was blue in the games and the anime; this was lampshaded in the latter.
 * Full Metal Panic is mostly realistic, but Kaname has blue hair (often described as black), and the Testarossa siblings are white-haired (often described as ash-blonde). Apparently, no-one finds this strange.
 * All the people that seem to have issues with this in FMP are Whispereds, and all sorts of nonsense can be attributed to this.
 * In Fumoffu, unnatural hair colors are given out like candy on Halloween. As you may have guessed, it's also the least serious season.
 * And then there are the manga covers, which give Sousuke either lavender or light blue hair for some reason.
 * All members of the Diclonius sub-species in Elfen Lied have hair in varying shades of pink (in the anime, at least). Justified in that they are not entirely human. Also, their hair color, combined with the cat-ear-like horns on their head, single them out among crowds of humans. Quite unusual for a manga, all the regular humans actually have realistic hair colors, and only the Diclonii live up to this trope. Only stand-out among the regular humans is Yuka who has blond hair, but is Japanese. However, we never see her parents, so she might have some Caucasian blood running in her family.
 * In the manga, the "third-generation" Silpelit, Mariko, has blond hair, which is completely impossible considering the fact that her parents were both Japanese and had dark hair.
 * Yotsuba Koiwai from the manga Yotsuba&! has green hair in colour shots. Everyone else's is normal and absolutely no-one talks about it. (Then again, maybe they just figure she dyed it--Yotsuba isn't exactly all that normal, even for her age group.)
 * The hair may be why strangers assume she's a foreigner.
 * Well, her adopted father did say he picked up overseas...
 * Banner of the Stars has a race of blue-haired space elves. Considering that the Abh were genetically modified to be able to live in space, to the point of having crafted a sixth sense for flying spaceships, the hair colour is really the smallest oddity...
 * Hair colors in Weiss Kreuz are mostly just implausible -- Aya, Manx, and Schuldig (justifiable as he is meant to be a white westerner) all have bright red hair, and Yoji and Omi are blond -- but some members of the supporting cast have outright impossible hair colors, such as Ouka's blue hair and, from the Oddly-Named Sequel 2: Electric Boogaloo series Weiss Kreuz: Glühen, Tsuji's green hair.
 * In One Piece, oddly enough, the blue hair of main characters Vivi and Franky is never so much as mentioned, while longer-standing main character Zoro's green hair is ostensibly unusual enough to be cause for mockery. Maybe his detractors just hate him a lot.
 * Odd hair colours might be considered normal, seeing as there are also a large number of incredibly tall or oddly shaped people like Gecko Moria or Bartholomew Kuma.
 * There are very few characters with green hair so it might be considered an oddity, whereas blue hair or otherwise is a lot more frequent.
 * As far as this troper can remember, Zoro, Keimi, Shojo (of the Saruyama Alliance), and Boa Sandersonia have green hair, and that's it.
 * There's also the Baroque Works navigator who took Bon Clay to Little Garden, but it's uncommon even on background characters. There are a few people with much darker shades of green too.
 * Takedo, the boxer delinquent from Kenichi: The Mightiest Disciple, has blue hair.
 * In Prétear, secondary characters have brown hair, except for Himeno's step-sisters, who have blueish-green and pink hair. The main cast got hair of different levels of plausibility: brown with some red mixed in (Goh), orange (Hajime), red (Himeno), blond (Shin), golden (Kei, who also has dark skin in the anime), and white (Mannen). Sasame was blond in the manga, but became white-haired in the anime (for a reason, apparently). Hayate's hair went from perfectly normal black in the manga to dark blue in the anime.
 * Most of the Trigun characters have realistic hair colours, but Legato has blue hair and yellow eyes to underline his weirdness, and some of the "mutant" characters have green hair, among others.
 * Princess Tutu falls somewhere within impossible and implausible. A lot of the characters have odd hair colors (Ahiru's hair is somewhere in between pink and orange, Fakir's is a dark, dark shade of green), but Ahiru could possibly be a stylized redhead and Fakir could have stylized black hair. Mytho's hair is white, but that could be justified, given his magical origins. But then there's Ahiru's friend Pique, who has BRIGHT purple hair -- so bright it's hard to think of as stylized black hair -- and Autor, whose hair seems to change between shades of blue or purple depending on the scene. And then there's Edel and Uzura's light green hair...
 * In Code Geass, the Japanese characters tend to have realistic brown or black hair, while the Brittanian characters have somewhat more outlandish hair colors and styles.
 * Theres also Mao and the Chinese Federation Empress Tianzi, who have gray/silverish hair.
 * Tianzi appears to be albino, complete with red eyes. Mao may be another example of albinism, as well. Possible, when you consider that, whenever his eyes are shown, they are always "geassed".
 * Also, Hot Scientist from India Rakshata Chala, who falls under the category of Dark-Skinned Blond.
 * C.C. has green hair which is apparently natural.
 * The anime series Captain Future, based on Sci Fi novels by science fiction writer Edmond Hamilton, created in Japan in 1978 and famous in Europe during the 1980s, featured at least one main character with blue hair and blue moustache (an older male character).
 * Rokudo Mukuro of Katekyo Hitman Reborn actually does have blue hair, in a sort of "pineapple" hairstyle that has been made fun of extensively by the fans and the author. Chrome Dokuro, the girl Mukuro saves//possesses/protects/etc. has purple hair in the same hairstyle. Semi-minor antagonist Nosaru also has purple hair. And at least three perfectly healthy, youthful characters have white hair (and one has gray).
 * Minami Juuji of Nabari no Ou has inexplicable green-blue hair. Raikou's pink 'do is okay, since he obviously dyes it (though he, his sister, his mother, and Yukimi Kazuhiko and Kazuho are all natural Japanese blondes). Aizawa Kouichi and Kuro'okano Shijima both have pure white hair, but this is because
 * Tengen Toppa Gurren Lagann is rife with examples of Anime Hair, since it's an over-the-top, hot-blooded middle finger to science. Heroes Simon and Kamina both have blue hair (though Simon's looks kinda black), Yoko has brick red hair (as does Gimmy), Leeron's is aqua, Darry's is cotton-candy pink, Kittan's is blond and black, and Nia...just Nia. Nia.
 * Green-haired Dayakka and purple-haired Kiyah.
 * Many of Gintama's cast members have reasonably realistic hair colors, but Gintoki's silver hair (which somehow appears light blue) sticks out like a sore thumb; this is actually pointed out within the series itself. Then there's Sacchan and Otsuu's purple hair, and Kagura's bright red-orange 'do (though this may be slightly justified in that she's not human.)
 * Rosario to Vampire has Kurumu as a straight example, while Mizore's hair is violet, sometimes close to blue (both of them inherited their hair colors from their mothers), and Moka is both the Rose-Haired Girl and the White-Haired Pretty Girl.
 * GaoGaiGar is somewhat...inconsistent about this. A hair color is normal, or at least unworthy of comment, if it does not come from alien heritage. (Hyuuma could actually have green hair, but it's almost certainly dyed, if so. And Akane probably actually has black hair.) But, Kaidou with red hair apparently looks much stranger than Kaidou with mauve hair. And Kaidou with mauve hair and Hana with pink hair are just as plausible as nearly everybody else's normal hair.
 * Max Jenius from Super Dimension Fortress Macross. Or Mylene Jenius (blue + green=pink? Who knew?). And Macross Frontier gives us Ranka Lee, with her green hair.
 * In Robotech, Max Sterling's blue hair is dyed.
 * In the case of Ranka and Mylene, this is probably justified, as it seems to be the case that odd hair colors are a natural Zentradi trait, and both of them have partial Zentradi ancestry; in fact, Ranka has inherited a rare Zentradi trait of naturally empathetic hair, so imagining that green is her natural hair color is hardly a stretch. Milia from the original Macross (Mylene's mother) and Clan Clang from Macross Frontier, both fully Zentradi, have green and blue hair, respectively. The odd ones are Alto, Nanase, and Grace from Macross Frontier; the latter's hair is blue, and the former two have purple hair. Zentradi ancestry seems fairly unlikely in all three cases.
 * In The Law of Ueki, the titular character has green hair, a likely reference to his power to turn trash into trees. The female lead, Mori Ai, has aquamarine-colored hair.
 * In a cast consisting of characters that mostly have "normal" hair colors, Death Note's Near happens to have stark white hair, while Matt sports unnaturally green hair, at least, in the anime adaptation and TCG (in the DS game adaptation, it became blue). Some images of L and Teru Mikami also have their jet-black hair mutated to more of a deep black-green, and the very first colored manga image featuring Mello depicted him with hair just as white as Near's.
 * Jun in the original Science Ninja Team Gatchaman had deep green hair that occasionally appeared black or brown in episodes, to the point where fans theorized that her hair was meant to be so black it only SEEMED "green". The sequel series and artbook images threw this into doubt, though, when her hair became a more obvious, brighter shade of green.
 * Many characters in Strawberry Panic have blue hair, as Shizuma complains in this fanvid. Shizuma herself has silver hair; Nagisa's is bright red, Chiyo's is blue-green, Hikari's is very light blonde, and Tsubomi's is pink. In fact, the only major characters with reasonable colours are the raven-haired Yaya and Chikaru.
 * No two Sibyllae in Simoun have exactly the same hair colour (including the two who are sisters). Among them, they've got the whole spectrum covered.
 * Normal hair colors are almost unheard of in Mahoraba, unless you're male, that is.
 * For the most part, RahXephon features almost entirely plausible hair colors. Almost. While Makoto's hair is explained as Albinism, there's still Quon's purple and Ayato's silver/gray hair to get past.
 * The girls in the Tenchi Muyo! series all have odd hair colors except for Mihoshi, who is blonde. Ryoko has what appears to be a very light shade of teal hair, Washū has pink hair, Ayeka has dark purple hair, Sasami has a teal-blue shade of hair with it's brightness depending on the series (sometimes it looks like light blue-green and sometimes it looks a bit sky blue), and Kiyone has dark green hair, though it can look black at times.
 * They're all aliens anyway, though.
 * Washū also has red hair, not pink, so she goes under barely normal in that area. Mihoshi is a brown-skinned blonde, and Washū is an age-bender...
 * Subversion of the escape clause: Aeka's purple hair is revealed in the manga to be dyed...it's actually the same light blue as her sister and mother.
 * Why is an alien bluenette dying her hair purple, you ask? To match her second mother's [Jurai royals practice polygamy] naturally purple hair! Said second mother is a full-blooded human from 13th century Japan, a fact which takes the escape clause, rips it into small bits, incinerates the bits with a flamethrower, and then urinates on the ashes.
 * Allegedly, it was about tweaking her available genetics to resemble her second mother, Funaho (who has black hair), as much as possible, hence her father's purple-hair DNA traits were turned more dominant.
 * Mikoto and Nara on School Rumble both have blue hair. Tenma appears to have purple hair.
 * Arale in Dr. Slump gets away with this because she's an android.
 * In at least the second series of the Ranma ½ anime, Akane is portrayed with light, rather washed out blue hair. In all other seasons, though, her hair is portrayed as either black or black with navy highlights. Shampoo, on the other hand, is a much better fit for this trope with a long mane of deep blue hair (although in some episodes, mainly the OVAs, her hair is more purple than blue). An anime-only episode reveals that, when she was eighteen, her great-grandmother Cologne had dark blue hair.
 * Anime Shampoo's exact hair color (blue vs. purple) spurred a vicious debate among fans at one point on message boards.
 * Ranma-chan's hair is deep, black-highlighted red in the anime, and has been portrayed in almost every color on the manga covers. It's noted in the anime that Kuno can't tell the difference between the red and black hair Ranma has in female and male forms, respectively.
 * Psyren. While in black & white the hair colors seem normal enough, but for the occasional colored section...
 * Tamahome and Chichiri from Fushigi Yuugi have blue hair of different shades (but the former's hair is often mistaken for green), while Nuriko,, and Empress Houki have purple hair. Chiriko's hair is a cross between brown and pink and the Nyan-Nyans have bubblegum blue hair. Tokaki, Subaru, and Tenkou have silver hair (this holds true for the former two even in youth), and Renhou and Miiru have silver-purple hair. Soi's hair is a shade of maroon, while Nakago is the only one who has blonde hair in the book world, and this is actually significant. The human forms of all the Beast Deities have hair in the color by which they are identified.
 * Shamanic Princess: Lena's hair is green and Sara's is light purple.
 * Hellsing Ultimate: Rip Van Winkle has blue hair.
 * The Harukanaru Toki no Naka de franchise is fond of this. Normally, if a character is blond (and has blue eyes), you can tell that said character is really blond and blue-eyed, which indicates that he either belongs to the Oni Clan if he is from Kyou or is not entirely of Japanese origin. The fact that the rest of the central cast makes up a nice rainbow when standing together (the anime adaptations enjoy the effect) doesn't bother anyone, and if you ignore certain characters who aren't quite human, it won't help anyway.
 * Specifically, among said non-human characters are two green-haired Artificial Human onmyoji and a White-Haired Pretty Boy who happens to be a depowered form of a white dragon-like deity, and none of them gets much commentary regarding their hair -- as opposed to blond characters.
 * In Aria, most everyone has normal colored hair, except for some of the main characters; Akari's hair is pink, Alice has green hair, and Athena's hair is lavender.
 * Wedding Peach has quite a few, including the eponymous heroine.
 * In Please Twins, this trope is even more jarring than normal - the three lead characters, two of which are siblings, have red, green, and purple hair. This is never mentioned, but their unusual (green) eye colour is several times.
 * In Fairy Tail, the main hero, Natsu, has pink hair. One of his companions, Erza, is a red-head (not orange-red. cherry red). Erza's antagonist character (since every character has one big bad affiliated with them), Gerard, has blue hair.
 * Erza's surname, "Scarlet", was actually given to her because of her hair color.
 * Mirajane in all her white-haired beauty. And Happy, who is a BLUE ANTHROPOMORPHIC CAT with wings that can fly.
 * And her siblings, Rob, Brain, and Angel as well.
 * A few other characters as well - Levy Juvia and Yuka Suzuki also have blue hair. The former Element 4 had odd hair colors: the aforementioned Juvia, Totomaru had white and black hair, and Sol had green hair.
 * Porlyusica, Sheryl, and Ikaruga have pink hair.
 * Lyon has a pale blue hair.
 * Bisca and Fried have green hair.
 * Bixlow has black and blue hair.
 * As well as the purple-haired Lucky
 * Crystal from Pokémon Special inverts this trope. She originally had brown hair, but was changed to blue to match her game and anime counterparts. She changed back to brown recently though, which makes people wonder what will happen in the Heartgold/Soulsilver arc..
 * On the cover of an Emerald volume, her hair was brown, but an image at the end of the saga shows her with dark blue hair. As of HGSS, it stayed dark blue again. But really, either the artist really can't make up his mind or he's trollin' us. Seriously, every time there's a colored shot of her, her hair color changes. Even her first outfit was like this; her jacket would go between white and pink.
 * Other Pokémon manga have their fair-share of this. Pokémon Re BURST has a green haired protagonist. Pokémon Diamond and Pearl Adventure has a blue haired primary protagonist and a green haired secondary one. Pokémon Golden Boys version of Kris has teal hair.
 * Diebuster has this in the form of protagonist Nono, whose hair starts out pink and turns into a glowing psychedelic swirl when . Given that this series is from GAINAX, makers of such refined weirdness as Abenobashi Mahou Shoutengai and FLCL, this is probably unsurprising.
 * Sieg Hart, Hardner, and (debatably) Belnika are the three blue haired examples of Rave Master. In addition, Haru, Gale Glory, and Let have silver hair. Ex-love interest Reina's hair is green, Nagisa's is pink, and, in the most normal case, Shuda's is cherry red.
 * Tazusa from Ginban Kaleidoscope has purple hair, her best friend's is green, and her rival's is dark red. Pete's dirty blonde hair is justified since he's Canadian.
 * The main cast of La Corda d'Oro contains a rainbow of unnatural hair colors. Let's see...Kahoko Hino's bright red, Len Tsukimori's blue, Ryoutarou Tsuchiura and Kazuki Hihara's varying shades of green, Azuma Yunoki's purple, Shoko Fuyuumi's bluish-green, Kanazawa-sensei's reddish purple, Shinobu Ousaki's the other shade of red, and Keiichi Shimizu's blonde. Lili is a subversion, since he's a fairy and it seems that he came with Seisou Academy's founder from Europe anyway.
 * Subverted because they're aliens, but the non-Earthlings from Magical Girl Lyrical Nanoha have some pretty wild hair colors, such as Signum and Caro's pink and the Nakajima family's blue. (Then again, you have to question how nobody picked up on the little girl in the wheel chair wandering around with a bunch of rainbow-haired foreigners in A's.) On the other hand, Nanoha's friend Suzuka is pure-blooded Japanese, and her entire family has purple hair. (Interestingly, that includes the maids, who aren't related to them as far as I know.) Nanoha's friend Alisa's blonde hair is an aversion, though -- she's not Japanese.
 * Rowan/Touma of Ronin Warriors has blue hair, which is unusual since this series tends to avoid giving the main cast odd hair colors. The 4 warlords, however, have brown, white, green, and blue hair.
 * In GA Geijutsuka Art Design Class, while some characters have acceptable hair colours--Professor is black and Kisaragi is deep brown), Tomokane is green, Nodamiki is pinkish-blond, and Namiko is a light brown. Lampshaded in one strip wondering why Western Animation uses Amazing Technicolor Population and Anime uses this. These are the characters' in-universe hair colours; Namiko and Nodamiki had to submit their child photos to the school to prove they had not dyed their hair.
 * In Sukisho, there's a pretty even mix between cast members with normal hair and those with weird colors. The series main characters, Sora and Nao, have blue and pink hair respectively. And then there's the little kids, two of whom also sport cotton candy colors.
 * Shadow Link, from the Legend of Zelda: Four Swords manga, is show to have purple hair, likely because purple is the direct opposite of yellow, and all the other "Links" are blond.
 * Bakemonogatari features Hitagi Senjogahara, a self-proclaimed Tsundere with purple hair. In the source material, she has brown hair, making this an Adaptation Dye Job. Given the animation studio's reputation, this would be considered tame, reasonable change.
 * Clannad plays this weirdly: the cast runs the gamut of rainbow hair colors...except for Sunohara, whose blonde hair is dyed and is stated to be "an impossible color" (his actual hair color is gray-blue). So...why exactly is that one shade of color impossible when none of the others are?
 * The other colors (except the Fujibayashi's lavender hair) are similar to black and brown, which are the main colors of Japanese hair. So it can be seen as an equivalent to that. Sunohara is full Japanese and can't have blond hair naturally. Not that it sounds any less weird.
 * Quite a few characters in Soul Eater have unusual hair colors, like Chrona (pink) and Black☆Star (blue). And the titular character, Soul, has white hair.
 * Neon Genesis Evangelion has more or less the normal range of hair colors, except for Rei's blue and Kaworu's gray. Then again, neither Rei nor Kaworu are fully human...
 * It has been suggested by some fans that Rei and Kaworu may, as a result of genetic tampering, have albinism. It's a reasonable assumption (very pale skin, red eyes). Hideaki Anno, however, insists that this was just to make them stand out against the other characters.
 * Misato has dark purple hair, though that might be a case of Hair Color Dissonance.
 * Star Driver appears to use impossible or improbable hair colors to denote Nominal Importance: the hair of background characters and extras are varying shades of brown or black, while main characters have red, blonde, green, blue, purple, or pink hair.
 * In Hidamari Sketch, Sae and her anime-only sister have cobalt blue hair. Natsume has green hair. Yoshinoya-sensei and new first-year Nori have green/blue hair. The remaining characters, even the important ones, have regular hair colors. (For the nurse, see White-Haired Pretty Girl.)
 * The Legend of Sun Knight: the Storm Knight must have blue hair, since the first one had blue hair. Every Storm Knight after him has had to apply blue hair dye every day as part of his role, and 8 out of every 10 has died from kidney failure due to too much hair dye.
 * Black Cat is pretty good about using normal hair colors for the most part, with a couple exceptions. Jenos' and Leon's dark green could be easily taken as stylized black, but Rinslet's bright purple and Sven's green stand out.
 * Mobile Fighter G Gundam averts this trope a good deal, with the only notable exception being Allenby Beardsly, who has sea-green hair. Apparently, in the future, the Swedish will all have this color of hair; one of her workers also has green hair.
 * Slayers follows this trope with purple hair instead: there's Amelia and her older sister Naga, the trickster priest Xellos, demonic general Hellmaster Phibrizo, the shrine maiden Sylphiel, and the well-mannered priest Rezo. Rezo's great-grandson, Zelgadis, has much lighter purple hair, as does Prince Pokota.
 * Lampshaded in Seitokai Yakuindomo: in the beach episode, a boy trying to get Suzu's attention explicitly calls her "kinpatsu" (blonde). No one else comments on her hair colour.
 * The heroines of Studio Pierrot's Magical Girl series have these:
 * Yuu from Creamy Mami is a weird case. When transforming into her Magic Idol Singer form, she gains curly lavender hair, but in her everyday form as a normal girl, she already has teal hair.
 * In Magical Stage Fancy Lala, the heroine's Older Alter Ego has blue hair, sometimes with green streaks.
 * Magical Star Magical Emi has green hair.
 * Persia the Magic Fairy has powder-blue hair in her younger form and magenta hair in her older form.
 * Magical Angel Sweet Mint has bluish-green hair.
 * Non from Majokko Meg-chan has blue hair.
 * While most of the characters of Future GPX Cyber Formula have natural hair colors, Bleed Kaga has green hair with orange streaks and a black braid tail for most of the series and Henri has silver hair with a red steak on a strand of his bangs.
 * Puella Magi Madoka Magica features characters with pink (Madoka), blue (Sayaka), green (Hitomi), bright yellow (Mami), and red (Kyouko) hair, as well as a character with grey hair at a young age (Kyousuke, bonus points for his parents having normal (dark brown) hair). Curtains Matching The Windows is the norm and characters that are Puellae Magi usually have the same color for their outfits (e.g. Sayaka has blue hair, blue eyes, and a blue outfit).
 * In Nerima Daikon Brothers, we have Mako (pink) and Yukika (red velvet, it would seem).
 * Hekikai no Ai ON:
 * Seine has green hair.
 * Yoshiyuki has purple hair.
 * Sheila has blue hair.
 * In Shinryaku! Ika Musume, Nagisa has cobalt blue hair, Chizuru's is more purple, and Takeru's is a dark teal. Ika herself may have hair, matching her blue tentacles, depending on whether or not that stuff over her apparent eyebrows is hair.
 * In Okusama wa Mahou Shoujo, people from Realm have various unrealistic hair colours. The rest of the characters have natural hair colours, though.
 * The Pretty Cure series goes through this in spades. While, with a few exceptions, those in Futari wa Pretty Cure and Futari wa Pretty Cure Splash Star have natural (or close to it) colors, it isn't until Yes! Pretty Cure 5 where the girls get widely colored hair, mostly in a wild case of color coordination. This doesn't even get into cases where their hairs change color!
 * In case you're wondering about those who follow the "blue hair" trope straight, it's Karen / Cure Aqua, Miki / Cure Berry, Erika / Cure Marine, Ellen / Cure Beat, and Reika / Cure Beauty.
 * In Saint Beast, several characters have unusual haircolors or two-tone effects. These include scarlet, white, bright purple, dark purple, teal, blue, pink-- the entire bubblegum spectrum.
 * In the Cyborg 009 movie Legend of the Super Galaxy, Albert Heinrich (Cyborg 004) has blue hair. In other adaptations, his hair is gray.
