When game starts notice the colors of the ingame menu or of the mouse cursor. Now when you turn to left or click the stool in front of you or turn to right 3 times, the colors of GUI and mouse cursor become a bit darker or maybe less colorful. This seems to change back at a later time.
No savegame, it should be easy to reproduce.
