Amazing Technicolor Population



"Saves A Fox: Okay, now try a skin-colored one. Grem: You mean a white one? K'seliss: She means a green one. Saves A Fox: I mean an orange one!"

- Goblins

In the real world, the color range of human skin is fairly limited. We largely come in varying shades of brownish, and even the most generous will generally only give humans four distinct "colors": pink, brown, red and yellow. This is to say nothing of proper ethnicity.

This is not so in cartoons. Animators, whether they're drawing cartoon characters or building models for a video game, have the freedom to make or draw anything they want. Thus, the normal range of human skin colors needn't have any bearing on the appearance of cartoon characters. Want your characters to be blue, orange, and silver? Go right ahead! Want a dude with a purple face to live next door to a green-skinned, not-from-space babe? The freedom's all yours, pal! If the characters are Genre Blind, their unusual skin tones will probably go unnoticed. If not, this may be Hand Waved in various ways or lampshaded.

Giving your characters unrealistic skin tones sounds like a great way to avoid Race Tropes and Unfortunate Implications, doesn't it? Well, sometimes. Unfortunately, it doesn't always work like this. If a character is meant to be of a specific ethnicity, they will most likely have the "correct" skin tone for their ethnicity, regardless of anything else. It seems as if only "white people" get Amazing Technicolor Skin—everyone else is left out. Still, it's a nice thought. Isn't it?

Compare Amazing Technicolor Wildlife (for animals), and You Gotta Have Blue Hair (for hair). See also Ambiguously Brown, for when the skin tones are within the realms of possibility, but not clearly "defined".

Anime and Manga

 * Zentradi in Macross (and thus the first Robotech saga) mainly have natural human skin tones, but quite a few of them have been seen to have purple, green, blue, or grey skin. In Macross Plus and Macross 7, we only see them with natural and grey skin color, and by Macross Frontier, they all have natural skin colors.
 * Mazinger Z: Big Bad Dr. Hell is purple. No indication why, since he's seemingly human.
 * All the members from the Noah family in D.Gray-man have...well, GRAY skin.
 * That's true of the anime version. However, in the original manga color art, they're also often drawn with skin in various shades of brown.
 * Not sure if this counts, but in a lot of series, people in flashbacks are shown to have completely black skin (possibly referencing kabuki theater). Revolutionary Girl Utena, for instance, gives everyone this treatment in flashbacks.
 * In Star Blazers / Space Battleship Yamato, Gamilons are shown with human skin tones until the episode where humans first encounter one face to face. From that episode on, they're all shown to have sky blue skin. Members of the second season's evil Comet Empire are all a rather icky shade of olive green (except Invidia, for some reason).
 * In fact, so many anime extraterrestrials have blue skin that it seems to be a kind of cultural shorthand for alienness.
 * For inexplicable reasons, Meg's rival Non in Majokko Megu-chan has an unhealthy looking white complexion. No one seems to mind, though.

Comic Books
"I been readin' about you, how you work for the blue skins and how on a planet someplace you helped out the orange skins and you done considerable work for the purple skins! Only there's skins you never bothered with -- the black skins!"
 * Pops up occasionally in the Marvel Universe. People with gamma-radiation based powers will usually be green-skinned, the Atlanteans and Kree are blue-skinned, and, occasionally, mutants have technicolor skin.
 * This got lampshaded in Exiles when, at one point, the team had two blue-skinned girls (Namora and Nocturne) and lavender-skinned girl Blink figured Nocturne's departure was because the group had too much technicolor skin tones.
 * Let's not forget Karolina from Runaways, who is an Amazing Technicolor Population all by herself...
 * Teen Titans has gold/orange Starfire, red Kid Devil, and green Beast Boy and Miss Martian.
 * Of course, both Starfire and Miss Martian are aliens, Beast Boy is a mutant, and Kid Devil was turned into a demon.
 * Occasionally seen also with people like J'onn J'onzz and yellow-skinned wacky men.
 * In a rare exception to the "only white people are multicolored" rule, Wonder Woman once dated the Hindu avatar Rama for a while, who is very blue.
 * Other exceptions would be grey-skinned Apocalypse (who, as an ancient Egyptian, would be non-Caucasian) and Skin (Latino), Sunspot (who turns really black when using his power), M's brother Emplate (grey), and possibly Penance (red-skinned).
 * Does the unnatural chalk-white Joker count?
 * The leaf-green Poison Ivy surely does.
 * Once famously lampshaded to discuss racial matters in Green Lantern/Green Arrow, where an elderly black man gives Hal a What the Hell, Hero?, saying that


 * And then, some years later, reversed (in a fairly light-hearted way) when a bunch of purple- and orange-skinned aliens visit Earth to complain that GL is neglecting the rest of his space sector to look after Earth; they use the same words with the colours swapped. Poor Hal just looks to the sky in frustration.
 * Doctor Manhattan is blue.
 * When the colorist remembers, Domenic of ClanDestine has light green skin. His older brother Walter's transformed state is consistently a pale blue color.

Film

 * In The Film of the Book of Coraline, Mr. Bobinsky is blue, for some inexplicable reason.
 * IMDb notes that he has a Chernobyl clean-up medal, possibly meaning he got radiated during it.
 * All the characters from the Land of the Living in Tim Burton's Corpse Bride are dull gray, whereas everyone in the Land of the Dead (the ones who still have skin, at least) are all bright blue.

Literature

 * In Terry Pratchett's Strata, the heroine is able to change her skin color at will when she feels like it; two examples are silver and jet black.
 * In Larry Niven's Known Space universe, "flatlanders" of Earth are a technicolor population, but it's just fashionable skin dye.
 * Steven Erikson's The Malazan Book of the Fallen has people of all colors that exist on earth, plus blue. (Which is mentioned very off-handedly and thus is very puzzling at first.)
 * In Monster by A. Lee Martinez, thanks to a survived basilisk bite, the titular character wakes up with a different skin color every day, accompanied by a random magical power. He keeps a notebook to track the powers that come with each color — up until he gains a measure of control over this condition with the aid of the story's MacGuffin.
 * Serroi, of Jo Clayton's Duel of Sorcery and Dancer trilogies, has green skin. Subverted in that it's very unusual and marks her as an obvious mutant.
 * Isaac Asimov's "Forward the Foundation" has a (human) judge with faint blue skin — the color gets more pronounced when she's angry.
 * The blue-skinned carnival freak from Mitch Albom's "The Five People You Meet in Heaven" (mercury poisoning caused his unusual skin color).
 * The Capitol and its inhabitants in The Hunger Games. They are stated to have ridiculous and freakish fashions, including body dyes.
 * The Uglies series hints at this in Diego. It's made clear that more 'Extreme' fashions aren't allowed in New Pretty Town but in Diego anything seems to go
 * In the web-novel Domina, Simon has purple skin, while his sister has jet-black. Probably just another cosmo; no one bats an eye at it.
 * The human inhabitants of The Darkangel Trilogy can have white (not pale beige), black (not dark brown), copper, amber, blue, green, teal, or purple (possibly two different shades of that last, no less) skin.
 * The inhabitants of Tormance in David Lindsay's A Voyage to Arcturus have many different possible skin tones, some of which don't exist in our spectrum.

Live Action TV

 * Muppets, anyone? Bert, Ernie, lots of the Anythings...
 * Savion's reading of "The Purple King" hung a lampshade on this.
 * Similarly, the "human" puppet characters in Avenue Q are green, blue, and orange.
 * Star Trek gave us blue Andorians and Bolians, Green Skinned Space Babes from Orion, and orange Talaxians with polka dots. Most other races just have whatever colorations Earthlings have, since make-up isn't free. Thus, Vulcans can be black, white, or Asian. Klingons were played mostly by white actors in brown shoe polish in TOS, but black actors played Klingons more often as of TNG.
 * "Let That Be Your Last Battlefield", probably the most Anvilicious episode of the original series, involved aliens who were chalk white on one side of their bodies and coal black on the other side. They were in a race war between those who were white on the right and black on the left, and those who were black on the right and white on the left.
 * For its part, the Star Wars Expanded Universe has a number of humanlike aliens and "near-humans" who are brightly colored. Most are explained as being normal humans in the far past who got separated onto different planets. Different living conditions and thousands of years' worth of microevolution resulted in people with blue and pink skin.
 * For instance, Twi'leks come in all colors of the rainbow.
 * The Doodlebops, a Canadian children's TV show. The cast are all brightly colored.

Mythology

 * In Hindu Mythology, some gods are often depicted with such skin tones. The most famous case is Vishnu, who's blue. Three of his avatars (Rama, Krishna, and Kalki) are also commonly depicted as having blue skin.
 * In Egyptian Mythology, Osiris is often depicted as green.

Tabletop Games

 * Being inspired by pulp sci-fi, the Dungeons & Dragons setting Carcosa features people that come in green, red, blue, purple, yellow, black, brown, orange, transparent, and white, plus jale, dolm, and ulfire in a Shout-Out to A Voyage to Arcturus, and neither black nor brown is negroid, and white is not caucasoid.
 * Starting in second edition, a number of existing humanoid races became more colorful, such as giants and genies who could now be green or blue or what have you. Prior to this, their skin and hair color had just never been mentioned.
 * Exalted has a few of these to go with the surprisingly-common blue hair, such as the Djala (nicknamed "Panda People" by the fans because of their white-with-black-patches skin).
 * New Horizon has Wafans, Ridiculously-Human Robots in any shade you can imagine.
 * Warhammer 40,000 generally averts this trope with humans, except for the Salamanders, who have jet black skin due to how their recruiting world is sitting almost right next to their sun. This is more noticeable in the recent edition, as previous editions had them with vaguely African skin tones, while the new ones just slapped on actual black with little regard for highlights.
 * The Orks have Green skin and the Tau have blue skin
 * Tyranids, to a degree, also have this, mainly because they're biologically engineered. Still, one wonders why a hive mind would consider flourecent pink with reflective metals to be good for camouflage.

Video Games

 * Saints The Third has various skin colors and lusters that do not occur naturally.
 * Artix Entertainment is always known to have it
 * Hero Smash has Yergan, a character with yellow skin
 * Psychonauts features a lot of blue and purple characters. It interestingly averts the "race" clause of this Trope—it features a green black girl and a bright lavender Spanish man.
 * Chops is a Black Canadian with red skin and green hair, though. And Milla Vodello is a Brazilian whose skin and hair are actually fairly realistic, if a little dark in the skin.
 * Blue skin also tends to mean "bad news": Both of the Final Bosses, along with Dr. Loboto and local bully Bobby Zilch, are colored blue, which leads to some Epileptic Trees of Luke, I Am Your Father.
 * The minor character Yoa in Beyond Good and Evil is blue. It's implied that she's "not a local," though she's still considered "human" to the game's scanner.
 * Bosco of the Telltale Sam and Max Freelance Police games is "light purple", but has an African-American voice. His mother is a more typical "black" medium brown though.
 * Hugh Bliss, who is genetically Caucasian, can change his skin color to colors of the rainbow.
 * Guitar Hero World Tour's character creation mode allows the full spectrum of color to be used for hair, beard - and skin.
 * Elemental War of Magic - your sovereign can pick any skin color, whether or not you're one of the dragon-hybrid guys.
 * The Sims 2. Every monstrous version of a sim has a different skin color. For example, alien hybrids are green, as are evil witches and plantsims (dark green and pale green with vines), vampires turn a shade pale, zombies become a greenish blue, werewolves are brown. Good witches don't change color, but apparently have glitter embedded into their skin for some reason.
 * Not to mention the endless mods you can download from the 'net which can give you just about any skin color you desire, up to and including rainbow.
 * The Sims 3 abolished the monsters (for now, anyway), but allows you to have exotic skintones right off the bat. In addition to normal skintones, there's also red, blue, and green. Plus, you can adjust it to any shade you wish. You can also set their hair or eye color to anything you wish and it will pass to their children. A man with blonde hair and a woman with black can have a child that has black hair with purple tips.
 * Many of the townspeople in the game Nox have fairly normal skin, but due to character customization, you can make the player character any color you want. Of course, no one notices if you happen to be a blue bald man walking around in your underwear...
 * In Yume Nikki, the Mall-like world is full of people of many different colors. The character Shitai, aka Dead-Guy-On-The-Pavement, has green skin. This is probably because he's dead and rotting, but a lot of fanart depicts him as a handsome man who just happens to be green.
 * City of Heroes allows you to create characters with skin in any of thirty shades spread across the rainbow or ten monochromatic shades from white to black in addition to a wide range of 'normal' skin shades. The NPC characters use this to a greater or lesser extent; for example, in the Outcasts NPC villain group, characters with ice powers have pale-blue skin, characters with fire powers have red skin, and characters with stone powers have grey-brown skin. The members of the Trolls NPC villain group all have skin that is a light green, a side effect of their use of the drug Superadine.
 * Geneforge. In the earlier games, only spellcasters had funny skin colors, but more recently, anyone could be blue, green, or hot pink.
 * The Fire Clan of Golden Sun have some spectacular skin colors. Among the major antagonists, Saturos is blue, Agatio is green, Karst is pink, and Menardi is white except for her ears, which are dark red. They also appear not to be entirely human, since they have scales, Pointy Ears, Facial Markings, and equally bizarre hair colors. It's never really in-game mentioned beyond "kind of strange-looking".
 * Turning into dragons wasn't obvious enough?
 * Again, it doesn't really come up in idle chatter, and, so what does that mean?
 * The Beastmen of Morgal in Dark Dawn also tend to get pretty outrageous fur colors, especially since they're supposed to be... well, animal-people. The band alone contains a bubblegum-pink Catgirl, a teal green fox, and a dark blue wolf. The king of Morgal is also blue-furred and has brown hair. Rather disconcerting.
 * Also in Dark Dawn, Blados of Tuaparang has blue-white skin. He was initially assumed by fans to be from Prox, but lacks the pointy ears and scales (and, you know, is from Tuaparang). Another character from his hometown looks entirely human aside from having Anime Hair and horns, so again, "not entirely human" might be the cause.
 * Inverted in indie-developed XBLA game series The Dishwasher - everyone has completely white skin, regardless of actual race. The Chef is, according to the sole creator, quite black, but appears just as ashen as everyone else.
 * The Double Dragon arcade games have technicolor palette swaps of the enemies in later areas, such as the green Abobo and blue Burnov.
 * In a world where every car has a different paint job, the Putt-Putt series is bound to play this straight. It gets even better when you find you can change his color. It always starts out purple.
 * Pajama Sam has light blue skin, as with most of the other "normal" characters in the series.
 * In Jak and Daxter, the Sages' skin colors correspond with the type of eco they're the Sage of. So Samos Hagai, sage of green eco, has green skin, the Blue Sage is blue, and the Red Sage is, unsurprisingly, red.

Web Comics
"Connie: So, why are you guys all blue? Slick: THAT'S RACIST"
 * All characters from Monsterful. We have blue, gray, green, pure white, scaly reptilian, even textured skin and more.
 * Justified, since they are all monsters living in a monster-only world.
 * The background characters in Supernormal Step are far more colorful than the main cast, and that's really saying something.
 * Schlock Mercenary has an engineered offshoot of humanity called "Purps", whose purple skin performs a type of photosynthesis, greatly reducing their need to eat (which can be a mixed blessing). And necessitating a change in police terminology.
 * A less cartoonish image of a purp is on the cover of Planet Mercenary RPG book.
 * Girl Genius: Agatha, Gil, and Tarvek change color every two panels in one of the arcs, due to a strange disease. Jägers can be any color from a "normal" human skin tone to green or purple, and some, like Mamma Gkika, change it at will.
 * The Law of Purple: Caligulan natives sport a rainbow of random skin colors amongst their total population - it's a species trait. So far, this includes blue, green, red, white, pink, yellow, silver, purple, and probably more.
 * Bloody Urban makes unrealistic skin tone a common trait of vampires. Even some of the human characters are odd coloured- Robin's friends Cherry and Myrcedys are greyish-pink and red, respectively.
 * I'm Not Mad started off with an Amazing Technicolor Population and then abandoned that after its second year (called season in the comic) reboot.
 * The gang of Blue Boys from Waterworks is composed of, you guessed it, four blue individuals. (Curiously, we see two of the thugs in a flashback and they're white back then, like all other people in the comic.) The protagonist lampshades it at one point.


 * One strip of NSFW fantasy comic Oglaf shows a Land of Indulgence where the population is this trope.
 * In Goblins, the goblins have multiple skin colors, even among the same clan (though there are hints that said clan is more cosmopolitan than most). This leads to the page quote.
 * Justified in Dreamwalk Journal and its spinoffs, because the planet Cyeatea's inhabitants are anthropomorphic insects and spiders. Between them they display all the colors of terrestrial insects and spiders, and more besides.

Web Original

 * In the MediaGlyphs Project, a bias-free pictorial language based on Chinese grammar, the genderless human figures appear in blue, green, orange, and purple.

Western Animation
"Judy: (Talking about Roger) Is he the blue one? Doug: That's Skeeter!"
 * The Simpsons. They're yellow, and the trope applies only to characters that are supposed to be Caucasian or Asian. The show creators said this was so people who were channel-flipping would stop to see if it was something wrong with their TV. The "Caucasian" characters can be called either white or yellow.
 * Interestingly enough, in the early seasons, the Asians were pale white.
 * It depends on what type of Asian you're talking about. Southwest Asians (Arabs and Indo-Aryans) tend to be rendered "white" (which is to say, "yellow") or "Mexican brown". South Asians such as Apu Nahasapeemapetilon or the Thai restaurant owner will be "reddish-brown" (like Native Americans). Chinese characters tend to be "white" ("yellow"), while Japanese characters are depicted either as icy pale (as if they were all wearing geisha or kabuki makeup) or "white" ("yellow"). Yeah, it's one fine mishmash.
 * Also lampshaded in an episode where Abe Simpson is considering marrying Marge's mother. Homer, concerned about he and Marge potentially becoming step-siblings, worries that their children will become freaks with "pink skin, no overbites and five fingers on each hand"...flash to a brief unsettling image of the Simpson children drawn as "normal" humans.
 * Krusty the Clown causes continuity errors with this trope. Depending on the episode, his unusually pale skin is either clown makeup or his natural color. However, that only seemed true in earlier seasons, and now it's implied to be due to Krusty's harsh, self-destructive lifestyle, with all his childhood flashbacks having him have normal skin.
 * The shorts on The Tracey Ullman Show featured background characters who were blue, grey, or orange.
 * Doug and his family were just about the only "flesh tone" people aside from Mr. Bone, Roger's cronies, and Mayor White—indeed, the most common skin tone in the Doug universe seemed to be purple. Interestingly, Doug's crush was a Dark-Skinned Blond.
 * For instance, Roger was green, Chalky was yellow, Bebe was purple, Mr. Dink was purple. Since Skeeter was blue (more like a dark teal, really), the prevalence of the Black Best Friend trope caused many to assume that blue is the equivalent of black in that world.


 * This was explained by the creator in a bonus feature from The Movie's VHS release. When first drawing the main cast (as a child!) he often lacked flesh tone, and therefore substituted other common colors for other characters' skins.
 * The Gangreen Gang from The Powerpuff Girls are exactly what color you'd expect them to be.
 * The somewhat obscure cartoon Angela Anaconda featured people with oddly toned clip-art faces.
 * Everyone had grey skin, and their hair and clothing would be in color.
 * All the humanoid "sprite" characters in ReBoot have unusually colored skin.
 * AndrAIa and Ray Tracer are borderline, since they're different shades of orange, a color which often results from cheap self-tanner in the real world.
 * Enzo runs into racial prejudice at the start of season three. For while, Mainframers will happily accept green merchants and scientists, though a green guardian is apparently beyond the pale...
 * Interestingly, this all suggests a kind of inherent caste system. Guardians are blue, the Matrices and probably other system-based sprites are green, and web-based sprites are orange. Viruses tend to be strange-looking in general.
 * In Voltron, the people from the evil planet (planet Doom in the English translation) are all different cool tones, including almost pure white, sky blue, deep cobalt blues, and even a green or brown earth-tone from time to time.
 * Serendipitously, this was true not only for Golion (Lion Voltron), but Dairugger XV (Vehicle Voltron) as well.
 * Blue skin seems to be Japanese cultural shorthand for "alien". In America, aliens are little green men; in Japan, they're tall blue dudes.
 * The Cramp Twins. Lucian has "normal" flesh-toned skin, but his brother Wayne is purple-skinned. Must be fraternal twins... However, both their parents have green skin.
 * Cupido is set in a town with white (as in snow-colored), red, blue, and yellow people, who are divided into ghettos by an evil council. The titular character and his two friends are the only characters with realistic skin colors.
 * The Thief and the Cobbler. The thief is green, the Evil Chancellor Zig-Zag is blue, and the cobbler is gray. The only person who has anything like a normal skin color is Princess Yum-Yum.
 * Not to mention Zig-Zag's minions (who are purple, pink, green, and gray), the purple-skinned One-Eyes, and the multi-colored populace of the Golden City. The desert-dwelling brigands, the witch, and King Nog all have relatively normal skin tones.
 * From Kim Possible: Drakken and the -Go family. In Drakken's case, incessantly lampshaded, and they constantly imply that there's a horrifically fascinating story behind his blue skin. In The Tag of the Grand Finale, he's about to tell said story when the episode series cuts out. "I remember it was a Tuesday-" *click*.
 * And Ron turns blue when he briefly goes evil, leading to the popular Tree that he's actually Drakken's son.
 * The Gross Sisters from The Proud Family are rather randomly blue, considering all the other characters are correctly colored and the series is all about ethnic diversity.
 * Several episodes imply that the "blue skin" is simply the result of the girls being extremely ashy. Yet, for some reason, it doesn't wash off in water.
 * Penny becomes blue when she "goes bad" in one episode. Apparently, if you ask the Disney channel, red or black aren't the "evil" colours -- blue is. Perhaps like the Blue Meanies?
 * Many dark-skinned black people who have ashy skin can sometimes appear as being a light periwinkle, almost faded greyish-black in the most extreme cases. Considering that The Proud Family is a cartoon with rather colorful art direction, it could be inferred that this was one of the most blatant exaggerations for artistic license.
 * The Fairly Oddparents' Francis the bully is gray. This is justified during an episode where Timmy wishes he wasn't born; in the alternate universe Jorgen shows him, Francis isn't a bully and is shown with tanned skin.
 * The gargoyles in Gargoyles have skin in just about any color. It's genetic, like hair or eye color.
 * The Children of Oberon (at least, the humanoid ones) run the color gamut, too. Puck is white (as in Caucasian), Oberon is light blue, and Titania is kind of green.
 * An episode of Fat Albert had the kids watch an episode of The Brown Hornet that dealt with a conflict between green and orange aliens.
 * Then, there's Chowder. I think that goes without saying...
 * Chowder and Panini count as Amazing Technicolor Wildlife though.
 * Nobody seems to make much of it within the canon materials, but Gorillaz bassist Murdoc is green. Some early pictures depict him with what could be a regular olive skin tone, but he slowly went through yellowish-green to his current dark green. This might be something to do with his unhealthy lifestyle (drug and alcohol abuse and a long period of living next to a disease-and-zombie-infested landfill). Wild Mass Guessing has also suggested it might be a sign that he has demon blood.
 * Apparently, Murdoc has some serious problems with personal hygiene, but it's highly improbable that just this would make his skin so green.
 * In Making Fiends, everyone is a single unnatural color, not just the skin, but the hair, eyes, clothes, etc. are all one flat color. Most minor characters in the webtoons were grey or dull in shade, although the TV series makes them all more vivid. Lampshaded pretty much every episode as Vendetta always calls Charlotte "Stupid blue girl!".
 * Some of the background characters in The Problem Solverz have colorful skin. The town's several mayors have had yellow and red skin, and in one episode, the gang was freaked out by a teacher who was purple.
 * In Thundercats 2011, the titular Cats of Third Earth employ the principle of Fur Is Skin. Panthro, who codes as a Bald Black Leader Guy, is pale blue-gray with black hair (a phenotype shared by Flash Back character Panthera, who, like Panthro, has a black voice artist). When the series reveals that more unconventional Humanoid Aliens also populate Third Earth, pink, yellow, and purple-skinned creatures appear, most notably, the lavender-complected Rubber Forehead Alien the Duelist.

Real Life

 * Ingesting certain silver-containing compounds causes argyria (silver poisoning, in short), the symptoms of which include one's skin turning a nice shade of blue. Certain other unhealthful conditions can cause red, yellow, or orange skin.
 * A particular enzyme deficiency can also cause blue skin. Read the Straight Dope on the Blue Fugates.
 * Neither one is a "nice shade" of blue. The usual comparison is to a bruise.
 * On a related note, prolonged contact with copper will turn your skin green. It's not a myth or something made up for that episode where the main characters get scammed on their class rings, it really happens and it's the primary reason why you won't see many copper ring bands, earring hooks, or anything else that stays tight to the skin.
 * Stan Jones, who unsuccessfully ran for Senate as a Libertarian, consumed home-made colloidal silver out of fear of Y2K problems, causing his skin to permanently become a blue-gray color.
 * Eating nothing but carrots for an extended period of time will turn your skin orange, most obviously your palms and the bottoms of your feet. The effect will wear off once you change your diet.
 * The Blue Man Group. Granted, it's really greasepaint, but still.
 * Curiously, the term in the Irish language for a black person is "duine gorm", which literally translates as "blue person". Makes you wonder how the above example would be advertised in an Irish-speaking town...
 * Likewise, in Old Norse, dark skin was described as "blue-skinned", whereas "black" would typically be reserved for describing hair color.
 * It's about hair. Even the term "Black Irish" is reserved only for black-haired Irish.
 * Jaundice, a symptom often associated with sickle-cell anemia and malaria, gives the skin a nasty, lemony-yellow color.
 * It can also be caused by drug addiction and certain vitamin deficiencies. It's essentially caused by damage or loss of function of the kidneys or the liver causing the skin to become tinted by things that you'd really rather were filtered out of your system...
 * The most common cause is actually alcoholism.
 * Albinos, heroic or otherwise.
 * Full-Body tattoos.
 * In a fascinating and extremely rare genetic disorder, certain biracial children have been born with a "stripe" down the middle of their bodies (particularly their stomachs)- a dividing line between the dark and the light skin. No, seriously.
 * Chimerism is more common in certain animals. Tortoiseshell cats have two lines of skin cells covering different parts of the body.
 * Some fake tan products don't quite get the color right and dye your skin orange instead.
 * A certain type of birthmark known as the Mongolian spot (warning: link contains picture of a baby's bottom) causes the skin around the lower back and buttocks in small children to appear blue. While most common amongst people of East Asian descent and Polynesians, it has been recorded in children across the ethnic spectrum.
 * As noted in the Word of God for the Doug example, kids without "proper" flesh-toned crayons/pencils/markers/et cetera will frequently default to more colorful options. Oranges seem to be common.
 * Strawberry marks aren't all that uncommon in babies, but some are born with unusually large patches of bright red areas due to those. Rare cases have them covering half the face or more - this can be corrected with cosmetic surgery, usually. Can also occur with children afflicted with large areas of hemangiomas - some of the skin will have the large, bright red masses, but other areas are just flat and red. This is also often dealt with surgically, especially if the hemangiomas get too large.
