Pink is a for girls. Purple is for Darker And Edgier girls.
As eveybody knows , Pink Means Feminine. But some Action Girl 's have something to say about it! Abandoning the more traditional pink color (too linked to Girly Girls, they now use purple as a way to show that they are both feminine AND strong at the same time. Authors generally use it as a way to either avoid the stereotypical pink for The Chick or to contrast a more traditionaly feminine character (who wears or use pink themes in some way) to a stronger/more action oriented one. Bonus points if a more traditional Pink Means Feminine trope is found next to it, though not required. Any instance of purple being the color for a Darker and Edgier girl is enough to evoke this trope. Examples: Anime and Manga
