I've seen the whole stadium in mostly white. It looks pretty good. But it's only mostly white because there is always "that guy". Sometimes that guy just doesn't know, and that is forgiveable. But unfortunately "that guy" tends to have some sort of weird personal problem with what the team is promoting, and a dogmatic disagreement with it. I've got to say, that's just kind of a strange thing to build up a religious fervor over.

If the team says "wear white", why not? It looks good. "Wear blue"? Great! It also looks good.

Besides, as a person who has attended many home games in a roasting late-August sun, I really like the white for those games.
