When my mother came home from work (in the 1950,s) she used to talk about all the 'coloured' people who were coming from the Caribbean to work at her place. I thought she meant they were red, green, purple, blue etc. and was dying to meet these people who were all the colours of the rainbow. Fortunately today there is no confusion.
