          The base16 colorscheme to use.

          You may use the name of a builtin colorscheme or an attrs that specifies the colors explicitly.

          Examples of builtin themes include:
          ${lib.concatStrings (
            map (e: ''
              - "${e}"
            '') builtinColorschemeExamples
          )}

          `:h nvim-base16-builtin-colorschemes` includes a full list of builtin themes,
          however the [plugin's source code] may be more up to date.

          You can access `require('${luaName}')` as `base16` in any raw lua,
          for example, you could reuse some colors from the builtin colorschemes:

          ```nix
            base03.__raw = "base16.colorschemes['catppuccin'].base06";
          ```
