The Weathering Cycle.
The surface of planet Venus is a stark reddish-brown colour. This is due to the volcanic rocks that dominate its surface.Due to the light spectrum that humans see with, the planet looks yellowy-white when we look at Venus from afar. The yellow tint that we see from afar is due to clouds of sulphur dioxide on the planet and is not the actual surface. So Venus isn't actually yellowy-white, it is stark reddish-brown.
From Earth, Venus appears a very light gray or tan, and pale blue near the poles. Some of this coloration is from the sulfur dioxide in its clouds. The only color photographs of the actual surface show a reddish coloration of the surface rocks, which could be oxidized iron compounds. If you look closely, it looks furry.
It comes from oxides of iron (like rust basically) which have covered a lot of the surface of Mars.
