title: WordPress Theme Customizer toolbar CSS
body: <p>How can I update the default WordPress Theme Customizer toolbar CSS so that I could for example change the text color from the default black.</p>
  
  <p>The default hook to add admin CSS does not seem to work here <code>add_action('admin_head', 'custom_admin_css');</code></p>
  
  <p>So for example the <code>#theme-description</code>  id, could be change to another color but how?!</p>
  
  <p>*I actually want to add some CSS to a custom option but rather than pasting lots of confusing code I am trying to keep the question simple, so If I can change the CSS for this then I can create CSS for what I need.</p>
  
  <p>Many thanks</p>
