If not, would a mainstream blood bank like the Red Cross be likely to have a problem with it, even if it's medically safe? (My character is an albino woman who is altruistic by nature, and I imagine if she thought she could conceal her albinism through the use of makeup and/or hair dye in order to donate, she probably would...as long as it's safe for her and for the potential recipients.)
EDIT: I have looked at blood donor restrictions, but I wasn't sure if there might be reasons beyond what the Red Cross and such might be aware of (by my understanding albinism is rare enough that it's possible). I couldn't find anything specific relating to albinism and blood donation through google.
