Using the NixOS module

After importing the NixOS module exposed by this flake, a colorscheme can be defined like this:

environment.graphical.colorschemes.purple = {
  image = ../../../external/6.png;
  params = [ "--lighten" "0.05" "--bold-delta" "0.1" ];
};

The generated colors will be accessible from environment.graphical.colors.purple as an attribute set of hex color strings:

nix-repl> nodes.ritual.config.environment.graphical.colors.purple
{ "0" = "#19172b"; "1" = "#453354"; "10" = "#90629a"; "11" = "#7a6d98"; "12" = "#9a79ab"; "13" = "#a6a1bc"; "14" = "#b69dba"; "15" = "#d0c5dc"; "16" = ""; "2" = "#734e7b"; "3" = "#62577b"; "4" = "#825d94"; "5" = "#8a83a7"; "6" = "#a07fa5"; "7" = "#b7a5c9"; "8" = "#2c294c"; "9" = "#5f4674"; }
