I teach High School Astronomy. The Sun emits light of all colors, but the most dominant color is yellow. For example, because the gas in the photospheres of other stars can be at temperatures different from the Sun's, other stars can have colors different from yellow. The photospheres of these stars are cooler than the Sun's, and so the most of the light from these stars are emitted from a lower energy or redder part of the electromagnetic spectrum.
Some stars look bluish.
These stars have hotter, and therefore bluer, photospheres than the Sun. Now, the question you asked is a bit different from the concept I just addressed. Because the Moon does not have its own energy source, it does not glow like stars do. Because it has a temperature, albeit very cold, it does emit a very faint and extremely red spectrum. However, this is not the radiation we see when we look at the Moon at night.
