As a color-blind player I find almost impossible to know, at night time, if the object I want to place (a sapling, a tree, a campfire...) is in a valid position, because the grey and red color change is less pronaunced at night. I'm sure I'm not the only one out there with this problem, and I assume that we would really appreciate if there was a color blind mode or something like that in witch the color diference would be more pronaunced.
