title: Change color of JTabbedPane border
body: <p>I'm trying to change the color of the default blue-gray border on my JTabbedPane. You can see the border circled in the image below.</p>

  <p>I want to make this a dark gray color. I've tried using the following <code>UIManager</code> properties (which result in the UI in the image above):</p>
  
  <pre><code>UIManager.put("TabbedPane.background", Color.decode(Colors.FACE_BG));
  UIManager.put("TabbedPane.foreground", Color.decode(Colors.FONT_WHITE));
  UIManager.put("TabbedPane.opaque", true); 
  UIManager.put("TabbedPane.selected", Color.decode(Colors.TABLE_SELECTION));
  UIManager.put("TabbedPane.border", BorderFactory.createLineBorder(Color.decode(Colors.DARK_GRAY), 1));
  </code></pre>
  
  <p>How do I achieve this? Thanks!</p>
