Good Terrain Colors

I am looking for good colors for an Afghanistan desert map. I am having trouble getting the colors right since I am doing different types of terrain. I’ll provide colors and the types of terrain I am having.

Types of terrain used:


What color values would you recommend for each? Thanks.

(If you would like to know more, please let me know)


Colors like dark Yellow, brown, tan, green and dark green(for the grass), dark orange, dark red.
That is at least what I am thinking about or I am thinking about the Mesa canyon

That sounds more like mesa, I am looking for like a lighter color

For that I think desserts sometimes have dark green plants and the color that comes to mind about them is dark yellow mixed with brown. And if sand comes into contact with water it becomes a little bit darker.
