A command-line tool that lets you change gamma in GNOME and Cinnamon (with Wayland). You can also adjust contrast and brightness. It works by creating a color profile with the VCGT table, so that changes are persistent and don't interfere with other settings like night light.
I just used this on OpenSUSE Tumbleweed to change the colours on one of my two screens. Works well, thank you!
Just wanted to leave the info here that the required package on Tumbleweed is typelib-1_0-Colord-1_0. Maybe you could also add this to your readme for future users.
