title: WordPress: Change admin wp_editor background color?
body: <p>I'd like my user to be able to dynamically set the background color of the wp_editor on the Edit Page screen.</p>
  
  <p>For example, I'm using the Iris color picker to let the user set a background color for their page.</p>
  
  <p>I'd like this color to be applied to the visual editor as they are editing, so they will see what it looks like.</p>
  
  <p>As a test, I tried modifying the editor's background color by calling: </p>
  
  <pre><code>tinyMCE.init({
      selector: 'textarea',
      content_style: "div { background-color: #000000; }",
  });
  </code></pre>
  
  <p>It didn't work.</p>
