This phenomenon happens when the only light reflected from the lunar surface has been refracted by the earth’s atmosphere causing raylight scattering, a similar answer to what causes sunsets and sunrises to be red.
What makes the Moon red?
The moon is fully in Earth’s shadow. At the same time, a little bit of light from Earth’s sunrises and sunsets (on the disk of the planet) falls on the surface of the moon. Because the light waves are stretched out, they look red.
