llenck/gamma

Small tool to change your gamma; not great, but source is easy to modify. This was designed to be mostly useful for keybinds in tiling window managers, for example i put this in my i3 config:

bindsym $mod+g mode "gamma"

mode "gamma" {
	bindsym Left exec --no-startup-id gamma -5
	bindsym Right exec --no-startup-id gamma 5
	bindsym Down exec --no-startup-id gamma -1
	bindsym Up exec --no-startup-id gamma 1
	bindsym r exec --no-startup-id bash -c 'xrandr --output HDMI-0 --gamma 1 && rm /tmp/gamma'

	bindsym Escape mode "default"
}
