Had we evolved under a red star, I'm pretty sure we'd be saying our star was "white". We have eyes which were optimised for the frequency spectra of our star.
I assume it's all relative, right? We could just as easily say there are hotness 1, 2, 3, 4, and 5. The question was, is ours perfect at a 3? And the answer was actually ours is a 4. If our star was a 1 and we evolved under that, I don't think it would change our perspective on the different hotness levels. A 4 would still be a 4.
