What might the surface of the moon look like (were you standing upon it) during a "blood moon" like last night? Would the ground have a red glow, or would it be too subtle to notice up close?

A blood moon is a result of the Earth's atmosphere filtering out the non red light which hits the moon, then bounces back, gets filtered again, and hits your eyeballs. It would be the same color you see, minus about 50-80% redness. The math would depend on the precise moment that you're talking about, because... atmosphere... spheres... magnetic... ugh. Too long, not doing it.
