All stars have colors, from red dwarfs and red giants, to white and yellow stars, to blue giants and supergiants. The color of a star comes from its temperature. As photons escape the interior of a star out into space, they have different amounts of energy. A star can emit infrared, red, blue and ultraviolet light all at the same time. They even emit X-rays gamma rays.
