Custom theme colors are not working

[rettimo]

NVIM v0.11.1
Build type: Release
LuaJIT 2.1.1744318430

MacOS 15.5 (24F74)

I want to make some changes to the base theme, but it doesn't work. I also tried to run :GithubThemeCompile, but it doesn't affect anything. What am I doing wrong?

Plugin setup:

{
	"projekt0n/github-nvim-theme",
	name = "github-theme",
	lazy = false,
	priority = 1000,
	config = function()
		require("github-theme").setup({
			palettes = {
				github_dark_default = {
					bg0 = '#000000', -- or any other color
				}
			},
		})

		vim.cmd("colorscheme github_dark_default")
	end,
},

Any updates?
