Ah, the green is more from the surrounding area... it's hard to explain, it's more silver than anything, but with a slight beige tint... technically they call it metallic pewter. The color's so light & neutral I think it's just picking up everything around it.
I like the smoking out idea... it'll be a while before I do anything to the exterior, but I see what you mean. As for the rims, I'm thinking black because of the tint in the back and the tires... keep the color scheme really simple, you know?
