At what skin colour is someone counted as being black?
What i mean is that some people are really dark black skinned, but some people are almost white but still counted as black even though they’re more like half cast… at what tone does a person become white?
Historically, the United States used a colloquial term, the one-drop rule, to designate a black person as any person with any known African ancestry.
