[meteorite-list] What are the True Color(s) of Mars ???

[j.divelbiss at att.net]

After years of studying rocks from Mars, pictures of Mars, and 500 days of closeup study of Mars with the rovers, does the science community have any idea about...

What color(s) would Mars have(look like) if the rusty outer skin was pealed back to the raw, unaffected rock? 

Mostly light colors ? 
same w/some Greens ?
Patchy w/whites and greens
Light green?
Green ?
Brown ?
Some brown and black patches with one the lighter options above?
Dark to black? 

I'd like to think it was mostly green with some light and dark areas. .

Imagine,
