You Gotta Have Blue Hair/Video Games/Visual Novel

Visual novels in which characters have unusual colored hair include:


 * Two cases in Shikkoku no Sharnoth, though one is a subversion. Viola dyes her hair the purplish shade that it is, but Claudia's hair appears to be naturally green. However, she's an extremely minor character and may be dying it as well.
 * Somewhat Averted Trope in Katawa Shoujo, where most characters have perfectly ordinary brown, blonde or red hair, and Misha's bright pink is immediately noticed as unusual. However, the hair color spectrum is still a bit too wide for a Japanese school, and some of the darker-haired characters have natural blue or purple highlights.
 * The school nurse, on the other hand, has light indigo hair.
 * Miou and Miku in A Profile have blue and purple hair respectively. However, since Miku's hair is referred to as black, it's likely that both of their hair colors are not what we see.
