That's the way I read it too.
It might help to know which of the three (black, red, green) will be the inner pinwheel that will "match" to the yet-to-be-chosen color.
However ... it's clear that you will need a light color to contrast with the other colors.
I think I would choose a white, or white with gold, or gold with white. Something with not too much print, plainish - to settle the eye.
