The words for colours typically followed after they were discovered and produced as a dye.
White is the oldest known colour to be used in art.
I suspect it’s because “pink” probably came along much later after “white” people were already around for a long time. And the word “white” is etymologically related to anything “light” or “bright”.
Had pink been used and known before white, then perhaps the first white people would have been called pink people.
