You are responding to a silly comment. With that said, I think straight black hair often implies non-european ancestry. I'd just assume main woman is Spanish, one in white is Asian. The non-black males are all pretty ambiguous (shrug)
We are talking about cartoons, so we're really talking about symbols and coding. You're taking too much of a leap by inferring that much about the underlying concept from the use of symbols. You might have a point, but you need different support.
What? I better tell some friends they aren't European.
