Pink and orange are not basic color words. They're the names of physical objects co-opted as a general color. It's the same for all the cultures that don't have a word for blue. Their users just refer to blue as the "color of the sky" or the "color of bird X". Same as English using the "color of this citrus".

I'd wager that if you go back enough all colors start that way. I don't really see that as relevant.
