          Murat Çileli has developed
          KWin Grayscale Effect which, according to this reddit thread is




          a fullscreen, configurable grayscale effect for KWin / KDE




          If you want this effect,




          • Download the tar and extract it.


          • Run sudo cp -r kwin4_effect_grayscale /usr/share/kwin/effects


          • Run sudo cp kwin4_effect_grayscale.desktop /usr/share/kservices5/kwin


          • And edit the [Plugins] section of ~/.config/kwinrc to have kwin4_effect_grayscaleEnabled=true on its own line. In case the [Plugins] section is missing from your kwinrc, just add it.



          To test it for the first time, open System Settings > Desktop Behavior. In there, open Desktop Effects. You should see Grayscale in the Appearance section. Toggle it a couple of times, and you'll see the grayscale effect at work.



          Grayscale off:



          Grayscale off



          Grayscale on:



          Grayscale on



          Further configuration is possible. From the gitlab link:



          A configuration file should be placed in /usr/share/kwin/effects/kwin4_effect_grayscale/contents/config/main.xml.



          And available parameters are:




          • ApplyInactiveWindowsOnly (boolean) : Effect applies to inactive windows only if it's set true.


          • ExcludePanels (boolean) : Effect does not apply to panels if it's set true.


          • EffectStrength (integer): Effect strength by percentage (%).
