When light from the Sun goes by the side of the Earth, it passes through a long and thick layer of Earth's atmosphere. Shorter wavelengths of sunlight, like blue, are scattered by the atmosphere. So by the time the light has finished its trip to the moon, more of the longer wavelengths, like red, are left over.
