A lunar eclipse doesn't turn the moon completely black, but copper red to brownish red. It can only happen during full moon. It is caused by the sunlight being refracted by the earth's athmosphere and that way being "bend around" the earth hitting the moon, which is completely in the earth's shadow. The refracted light (also called secondary light) is red, like the light of the sunrise/sunset.

You see, blood moons and lunar eclipses are exactly the same thing.
