Base 16 colorschemes can have many applications. If the instructions for your use case are not listed here, please feel free to open an issue or pull request.
To use the cyberdream base16 colorschemes with Stylix add the following to your configuration.nix:
{ pkgs, ... }:
{
stylix.base16Scheme = builtins.fetchurl {
url = "https://raw.githubusercontent.com/scottmckendry/cyberdream.nvim/main/extras/base16/cyberdream.yaml";
sha256 = "1bfi479g7v5cz41d2s0lbjlqmfzaah68cj1065zzsqksx3n63znf";
};
}Pay close attention to the sha256 hash. Especially if you are using the light variant, the hash will be different. NixOS will tell you the correct hash in the error message if you get it wrong.
