or deep black skin (which requires inheriting alleles for dark skin on all or almost all of the requisite genes),
IIRC, skin coloration, including the deep black, is partially climate induced. It takes something like a 1000 generations to make a shift from pale to dark, but it happens. So as long humans keep living in a variety of enviroments, people will look dramatically different from one another. Evolution demands no less.
