Light Feminine and Dark Feminine

This is a character contrast trope. Both female characters are decidedly feminine, but in different ways. The Light feminine is generally angelic and feels love. The Dark feminine is generally devilish and plays with desire. Either type can be the girly girl portrayed in the Tomboy and Girly Girl contrast. When a love interest is involved, it's likely to lead to a Betty and Veronica love triangle: Betty being the Light feminine, and Veronica being the Dark feminine.

As with any two character trope, the two characters have to have some sort of relationship with each other, be it friends, family, love interests, or rivals for a love interest, so the two characters can be playing the traits directly off each other.

The dark feminine character is not a villain or a whore but half of a good girl, bad girl or naughty and nice pair. Remember not to put a square peg in a round trope. Remember Dark Is Not Evil.

Compare The Three Faces of Eve. The Spear Counterpart is Noble Male, Roguish Male.

 * In Yu-Gi-Oh, Mai Valentine/Kujaku plays Dark Feminine to first Tea/Anzu's and then Serenity/Shizuka's Light Feminine.

The latter is an elegant and aloof Ojou who also loves Mytho, but in a far more possesive way. Both girls have white and black costumes of their respective Magical Girl personas, Princess Tutu and Princess Kraehe. Also, they're both based on Odette and Odile from the ballet Swan Lake.

Despite all this, they're also best friends.
 * Ellony Leckery and Pharinet Palindrake in Chronicles of Magravandias, Ellony being a straight example of The Ingenue while Pharinet is something of a Yandere when pushed.

She falls more into Tomboy and Girly Girl with Farina and Lyn, and with Ninian it's unclear because they are both very Light Feminine.
 * Fire Emblem the Sacred Stones gives us Eirika and L'Arachel. Eirika is a gentle Lady of War and The Messiah, L'Arachel is a bombastic Genki Girl.

Western Animation

 * Adventure Time: Marceline is the Dark Feminine, while Bubblegum is the Light Feminine.
 * My Little Pony Friendship Is Magic:
 * Fluttershy (Light) is kind, caring, very much like a mother to the animals. Rarity (Dark) is vain and slightly manipulative, but still a good-hearted pony.
 * This contrast is also readily apparent in the princesses. Celestia tends to act motherly and patient towards her subjects, while Luna is more intimidating and impulsive.
 * Another possible pair of characters to display this contrast is Pinkie Pie and Twilight Sparkle. Pinkie is Light, in that she tries to make everypony happy and operates primarily on intuition. Twilight is Dark, having a prideful and slightly selfish streak and operates primarily on logic, although, like Rarity, she's still a good-hearted pony.
