Exactly. I'm in my late 40s and saying someone was "black" in the 80s was not cool at all. More recently it is seen as a positive because African-American is not necessarily accurate or inclusive 

It's all about keeping up with the times

Yes, in the 90's I was told not to use " color" words to describe people. So I avoided the terms. Now it's OK to say black, or brown people. For the record, I'm of non- European descent.
