Stars do not maintain the same temperature, therefore they all have different colors. Which of the following star colors is the hottest?
Answer Blue
A star's color is determined by its temperature. Red stars are the coldest, while blue stars are the hottest. And the only factor that determines a star's temperature is its mass. For example, blue stars are at least 3 times larger than our Sun.
