um, the only thing i would say about using just black, as a person of color, is as stated above, all those groups name themselves as black. i generally think of myself that way. but i don't look like i come from africa. i don't know about the political connotations of your item, but i think the name should be both catchy and informative. quim2001's Zulu is the sort of really deep chocolate the name implies. dalinise's brown sugar (not daz's) is the sort of medium mix that's common in america. i actually remember a thread where people were posting what they wanted most in a vicky 2 set. almost everybody said more diversity, and one person notably said someone african and not cafe au lait mixed looking because there were already enough out there. this isn't to say that there aren't tons of different looking types of people of color in every nation, on every continent. either way, i think your name should give some sort of indication of the character's style. what niche do you want to appeal to? what makes this character special? is this an average guy/gal or a fantasy/sf type? whatever your intent with building the character, i think the name should match.
