If you can read the story and still get the message without adding the race of those involved, then race is not a necessary addition.

Honestly I prefer people are identified by their tribes or families. It is more specific than using vague colours. I have never seen a white human being yet we have been programmed to all ourselves white. You mean white like salt? That’s what I mean when I say white. Use tribes or families to identify people. Much better than vague colours

I tend to avoid stories like that because its obvious the author is trying to push in a racial divide amongst its readers.
