The word BLACK came from the language of white people not from Africans.It was only in the 16th century that we saw the meaning change of blac to refer to something dark (night-colour): The word ‘Black’ can be traced back to its proto Indo-European origins.From the 18th century to the late 1960s, NEGRO was considered to be the proper English-language term for people of African origin.
In (European) white people language Black has always had negative association links BLACK death, BLACK magic, BLACK mail, BLACK evil, etc etc long before the white people even met African people in late 15 century.
