Stars, or at least most of them, are big fusion machines. And they generate almost unimaginable amounts of energy doing this. Light is one of the energy forms that stars give off, and the color of the light will depend on what the star is doing for fusion (what elements it is fusing), and what elements are present within it. There is another factor. For the most part, stars outside the Milky Way, except for Andromeda and a couple of other galaxies, are in galaxies that are moving away from us. This changes the color of the light we see because of Doppler effect. The receding galaxies, because they are receding, Doppler shift the color of the light we see toward the lower frequency end of the spectrum, which is the red end. This is why we use the term redshift when we talk about the light from distant stars in distant galaxies. The color of the light we see is shifted toward the red end because the distance between the source and observer (us) is increasing.

Why are seastars different colors?
Sea stars are different colors due to pigments in their skin called chromatophores, which can produce a range of colors. These colors may help with camouflage, predator avoidance, or communication with other sea stars. Additionally, some species of sea stars can change color depending on their environment or activities.
