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?

It would be much more surprising if they didn't have any colour. How would that even work?

I expected them to be white and white is a non color, as far as I know.

White is just a mix of all the colours.

Talking about stars and light, white is the opposite of a non-color. It's all the colors all at once. Black is the only nob-color. Our sun isn't actually white, it emits a broad spectrum of light which appears white to our eyes, it actually emits more green to blue-green light than anything else. Look-up the sun's spectrum or the main sequence of stars and you'll see what I mean.
