"black" is such an inadequate label. I live in the UK; we get a different mix, perhaps, to what's visible in the USA. Not just Africa but India. There are some pretty dark-skinned people coming from Southern India. Anyway, I tried to have a look at the soles of my feet (and fell over). I'm definitely white, and I don't think there are many "white" textures that get feet and palms right.
