I was wondering if there were any African American LEGO minifigures besides the ones from the sports basketball series... I got a brown head from a LEGO Stormtrooper set instead of a black one. I then painted it. Do any other sets have them?
There are a few on Bricklink, if you search by part colour:
If you search for the older Brown colour (instead of the current Reddish Brown) you find that there are basically only the very rare Lando head, as well as the old NBA heads.
Minifigs from licensed sets are made to look like their license counterparts, so there are some there, most notably Star Wars Mace Windu and Lando Calrissian which have both been made in 4 different versions.
As for non-licensed sets, I don't see any other than the NBA ones.
