Earth Tones

Before the introduction of this poisonous gas called oxygen, the Earth would have appeared green from outer space. To this I say, "Thank you, oxygen!" I would hate to clash with the other heavenly bodies in our solar system. Green Earth and orange Mars just sounds like a bad 70's shag carpet. And given the yellow Sun if Earth were green we would have to call it the LemonLime System - which is just wimpy!
