I don't know if this particular issue has ever been discussed, but it involves creating an NPC. In the Fallout 3 GECK, I create a human female NPC. By default, the NPC starts out as Caucasian, but I wanted the NPC to be African-American. The NPC's head was changed to the assigned race, but her body is still Caucasian. Even in-game as a little test I decided to conduct for myself, her body is lighter than her head. What seems to be the issue?
