I find the default color intensity to weak. It makes the environment look a bit pale while it could look more lively. Especially the grasses tend to look a bit brownish green instead of real grass green. The different types of terrains pops out less then it could.

Because this is purely personal preferences I would love to see a slider in the video settings that can increase/decrease color intensity. Or by default add more color to the game.

I made a few screenshots and edited the color intensity by 15% and I personally find it looking a lot better.
