ELI5: What causes the Redshift as seen in last nights lunar Eclipse?

Would it be correct to assume it has something to do with light passing through the Earths atmosphere?

It's not redshift, that's caused by going really fast.  

But yes, it was light passing through the Earth's atmosphere.  Basically you were seeing the same thing as sunrise and sunset on the Moon through the Earth's atmosphere.
