I was taking a class of year 7s in a school in the UK around 6 years ago. They were aged just over 11 years old. Quite a well behaved class and all sitting around an arranged square of tables. A commotion started between two pupils sitting next to each other, one a "white" boy and the other a "black" girl. The young boy complained to me that the girl sitting next to him was calling him a "whitey" and the girl complained to me the boy was calling her a "blackie". So I asked the class to find me a plain black sheet of paper and a plain white sheet of paper. Then I got the pupils to present their hands and did the "shades" test with the sheets of paper. Yes the boy wasn't "White" compared to the white sheet of paper , more pinkish dark white and quite a stark difference with the white sheet of paper. The girl wasn't "black" but in fact a dark shade of brown. So, I told them neither were white or black. The class and the two kids fell silent, and peace was restored. Differences are used for domination and bullying and are just concocted pretexts. White and black are colonial designations need to be removed from colonist vocabularies.
