Now that the word black is politically incorrect What word can we use instead of black ?

As always, so much depends upon context. The situation, the individuals, the relationships. I know a former colleague and still long time friend who was a Black Panther back in the days of Black Power. We have the sort of relationship in which she refers to herself as the Chocolate Bunny and I will call her that as well -- but we have that kind of relationship, and I wouldn't do it in public or a work setting.

Communication is all about knowing your audience, and matching semantics to situations in order to communicate rather than trying to provoke.
