person of colour, n.phr., is to be distinguished in sensitive discourse from coloured person. Whilst usage of the first is presently (as of 2:53pm gmt on 29th January 2015) recommended by coloured people, usage of the latter may land you in trouble because it is not presently (id.) recommended by coloured people, though it once was. Person of colour is often abbreviated to poc, presently (id.) without disapprobation. The plural is pox.
