My point was that the words are vaguer, and so less easy to comprehend. White is a colour, pink is a colour, green is a colour. Taking the words literally, everybody is a "person of colour". You can't directly intuit the meaning of the phrase, it requires acquisition of the specific cultural meaning. But good point about the diversity aspect - you're right, that is a good reason to make the terms more inclusive.
