Dark mode selector background colors

I easily replaced the sun and moon on my forum with the yin-yang, by putting this in the head tag of edit / css of a component (i also replace the bot icon with a lightening bolt).

<script type="text/discourse-plugin" version="0.8"> 
  
  api.replaceIcon('robot', 'bolt');
  api.replaceIcon('sun', 'yin-yang');
  api.replaceIcon('moon', 'yin-yang');

</script>

I just found it easier to do it that way.
