The game has a strongly saturated look with red/violet as dominant colors, which is a little bit too much for my eyes. I've made a lut, that I use in conjuction with Reshade to reduce the colors a bit. Maybe some of you have a use for it too. See attachments.

edit:
Another solution is to open the debug editor by pressing F1, go to "Rendering Control" and double click the file under the "Lighting" tab. This will open a window where one can change everthing about the lighting and colors of the current level (click "Save changes" if the settings should survive a restart).
