So in my story I have a character named Color Stargazer. But she just goes by Color/Colorful. Anyways, she has a unique version of Vitiligo I like to call "Rainbow Vitiligo." The reason why I call it that is because her skin, hair, and eyes are constantly changing colors. So one panel she might have dark skin with white hair and white patches, but on another panel she would have light skin with red hair and brown patches. But since this is anime she would have more hair and eye colors to cycle through such as: Blue, Green, Orange, etc.
I've read online that its possible for areas affected to revert back to normal, either through treatment or naturally. (That's how I got this idea to begin with.) So THERORETICALLY it should be perfectly possible for a person with Vitiligo to regain pigmentation in one area and lose it in a different area. Of course if this were to happen in real life the changes would take years to happen rather than minutes.
So my question is; Would this actually be able to happen in real life?
Normally I like to ask my discord these weird questions but the server was so divided that I couldn't get a definite answer.
