I’m wondering if there are possibly any tools out there to do this: Declare a color scheme and set them to all apps CLIs and TUIs, either immediately on upon restart of each app individually. I’m on NixOS and looked at Stylix, once properly set up it automatically sets color schemes to apps. To change the color scheme I’d have to rebuild my nix configuration which is slow.


In case you happen to be on KDE,
plasma-apply-colorschemegets you pretty close, especially if you’re mostly using KDE programs.
