Appropriate Material for a Red Moon
I have some ideas regarding this, but thought I would check to see what you guys can come up with, as I found some of the ideas here often trump mine in originality and/or plausibility.
So, I have a planet which has a moon orbiting it, but instead of the white/yellow-ish glow that our moon gives us, I want to give it a different color (for example such as Io wich is Yellow due to sulfur).
What I want to know is what kind of stone/mineral/material could I have this moon to be made of in order to give it a red glow? (and I mean ruby like red not the orange like red color that Mars has)
P.S. would having a moon with such a different color have side effects on the plant and animal live on a planet, if it were otherwise comparable to earth?
