[rquote=2510236&tid=145002&author=jgfrise]I remember Rachel asking him if he was black? She didn't realise he was a negro until about half-way through the series. Don't think she understood the concept of "albino" at all.[/rquote]

Darnell was not black.

"The term black person usually refers to a racial group with skin colors that range from brown to nearly black. It also has been used to categorize a number of diverse populations into a common group. Some definitions of the term include only people of recent Sub Saharan African descent."

So he was not dark skinned nor of recent Sub Saharan African descent.
