The Moon will be eclipsed by the Earth tomorrow morning and there will be a blood (red) moon due. That means that as the Earth moves between the Sun and the Moon the light rays from the Sun are refracted by Earth’s atmosphere. Blue light is scattered more but red light continues towards the Moon and illuminates it. (in a similar way that at sunset the sky can turn red).

Moonlight has been important in my life, from the Moon landings from 1969 and seeing it in its various phases. I remember being in my bedroom sitting on my bedroom window ledge as a child and reading books by moonlight. I loved being able to read even though we had to turn the lights out. I used to enjoy it.
