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?

    Most of the more exotic colors (such as green) are caused by various optical tricks.

    Physically speaking, all true stars are roughly one of these colors:

    • Red
    • Orange
    • Yellow
    • White
    • Blue

    The exact color of a star depends on its size/temperature. Red stars are the coolest, while blue stars are the hottest.
