[quote=Kidd]As for Yang having purple eyes--which are possible in real life anyway, though typically only seen in albinos funnily enough--Ren also has pink eyes. Both of their names are ethnically similar and seem to reference the Oriental. On that, I just assume that these odd colored eyes are typical of people of pseudo-Asian decent.[/quote]

It's anime-based. Does hair and eye color have to make sense beyond looking attractive?
