title: How to get the source lists selection highlight to use the Dark Vibrancy appearance in OS X 10.10?
body: <p>In OS X 10.10 source lists seem to use the <em>light</em> vibrancy appearance. In the Finder (and in some other third party applications, Things.app for example) the selected item in the source list is indicated by a <em>dark</em> vibrancy appearance. For example, see the Desktop row in the image below.</p>
  
  <p>How can I replicate this behaviour? Do I need to use the delegate methods to specify the table row view,</p>
  
  <pre><code>-outlineView:rowViewForItem:
  </code></pre>
  
  <p>and attempt custom drawing myself or is there a more straight forward approach? If you make a standard source list UI in Xcode the default highlighting is remain the standard blue rectangle that we have seen in previous version of OS X.</p>
