There is already a request for color adjustment here. Please go and vote.
We need the ability to adjust colorspace, not just ask for it to be ‘fixed’, because we perceive it differently and are using a wide range of different types of screens etc.
I find the ground colors very bland and undersaturated compared to real world from altitude. I also find the vegetation is (for the most part) too blue. I’ve used an image editing package to adjust your screenshot in the lower left corner. This looks way more natural to me. I used a tone map adjustment to move blue to yellow (particularly in highlights) and then desaturated a bit. Desert textures mostly seem to be okay.
