Because there's no life and no vegetation, that barren landscape you see high above the mountains would go all the way down to the base of them mountains. At the mountain's base, you would get deserts of quartz sand, slightly yellow. Think the sand dunes of the Sahara desert. This sand comes from the breakdown of the granites. Quartz, the most resistant mineral in the granite forms sand, I guess from the action of wind. The other minerals (mostly feldspar) break down to form all kinds of clays, aka dust. So to sum it up:
Most of the surface will be covered by dark red low lands, with high lands of sandy desert and Himalaya type mountain belts sticking out of them.
