SpecialKey is highlighted the same way as text

[ArtAndreev]

Description

Invisible characters like <CR> are printed like ^M in vim and in another color. The colorscheme doesn't distinguish text and them currently:

nvim -u NONE:

This makes it hard to understand this is a text or a special character.

:hi SpecialKey says:

:hi SpecialKey
SpecialKey     xxx guifg=#cdd6f4
:hi Normal
Normal         xxx guifg=#cdd6f4 guibg=#1e1e2e

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "catppuccin/nvim",
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("catppuccin")
-- add anything else here
