Actually, all in all, we could just go with pure white. White moves first, and I've seen a few (I have one at home) chess sets which are variations of white and entirely transparent.
So, what say you guys? If I get a majority of positive replies, I'll post in the Team List.
EDIT: Well, okay, maybe not white but a colour reminiscent of frosted glass or something. Seeing as white already exists as a team.
