title: Changing jupyter's matching parenthesis color
body: <p>How do I change the color of the matching parentheses in jupyter? Regular, square, and curly brackets all appear in bright green when they are shown as matching pairs and it is pretty difficult to see in light background.</p>
  
  <p>Modifying <code>~/.jupyter/custom/custom.css</code> by adding <code>.CodeMirror-matchingbracket</code> doesn't seem to do anything for me.</p>
