Honestly I am undecided. Studies on evolution are always providing new and sometimes surprising information so human origin theories are always changing and evolving themselves.
From what they are saying now, our DNA is originaly coded for brown eyes and brown hair. Other eye and hair color are gene mutations either caused by climate adaptation or from inbreeding.
They have found some neanderthals in Europe to have light skin and red hair, so it may be possible early humans did as well. If I had to guess, I would say the base gene for skin color / melanin production is probably something in between what we think of as black and white, maybe something akin to medeteranian / middle eastern complexion- ancestors to the north developed paler and ancestors to the south develped darker.
As for what colors monkees are under their fur, the closest relative to us on the monkey chain is the chimpanzee, and they really aren't white or black, they have speckled pigmentation almost like freckles. Here are some bald chimp pics so you can see what I mean.
