Prerequisites:

bc, xcalib, xgamma, picom

Usage:

Correct paths in scripts if needed, by default it is ~/scr (you may just clone repo into home dir)

Bind scripts named *-more *-less *-reset to hotkeys

Run profile-save.sh or profile-load.sh without args for info

Disable any other compositor for picom to work

Notes:

Picom uses shader to modify saturation as hack for graphic drivers/GPUs that doesn't support native methods
