Black. Brown. White. Yellow. I don't mean to sound rude, seriously! That's skin colors, and it's a critical part of describing someone. I could describe a man down to his top hat, monocle and twirly moustache, and you'd still let him walk right past you if I said nothing about skin color and he turned out to be black and not white as one would correctly assume from the highly stereotypical outfit I gave him.
I don't see the problem in just using the skin color to describe someone. There is an exception for me though, and that's yellow. Not because I consider saying that wrong really... It just doesn't flow very well, it gets stuck in my mouth and feels clumsy. So I'd rather say asian, indian, middle-eastern, black, white, spanish... Well I don't know... I seem to take a slightly more direct route in describing someone.
Oh, and he drinks tea. Lots of tea. His name is Lord Sippencup. And he IS black.
