title: termguicolors in vim makes everything black and white
body: <p>The idea is that by using <code>set termguicolors</code> in Vim, I should get the colorscheme (gruvbox) to look in my terminal (<code>st</code>, has true color support) exactly like in GVim. But all I get is white text on black background.</p>
  <p>The part in vimrc which sets the colorscheme:</p>
  <pre><code>set background=dark
  colorscheme gruvbox
  set termguicolors
  </code></pre>
