Adding to the previous reply ;)
Mods stated here provide slight fixes to the lighting to make the game more pleasant looking (less darkness, less blue shadows etc.) -

If you are looking for some more 'atmospheric' lighting, I can recommend mods by softerhaze - https://softerhaze.tumblr.com/tagged/s4cc (github repository https://github.com/ts4cc/lighting-mods)
And for more drastic changes, complicated effects & options you can download reshade + use premade presets (you can find some here https://maxismatchccworld.tumblr.com/tagged/s4-reshade)
