Star actually have colors (lemmy.ml)

While camping, I noticed that if you look long enough at almost any star, you start seeing some tiny, subtle colors in that star. Even crazier, they sometimes flicker between more colors. In my case orange, blue and something like cyan.

Besides constellations, what else could you observe regarding starts, with the naked eye?

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.
