Humans happen to be far more flexible than steel...you know, with all that cognitive thinking, either way the whole brown bag logic is flawed, since DNA testing has already proved (yes even from Tribes of all sorts) that there is a mix however small it may be. We're picking at straws if we decide to think someone can't consider themselves "black" because they're mixed. In context to the video game character, I already addressed she would be considered creole, but that's ethnicity, not some flawed rating of melatonin.
