title: Setting background color to JButton
body: <p>I have a question about setting the background color to <code>JButton</code>.</p>
  
  <p>It seems that the this method only changes the color of the border. Here is the difference (left is <code>jButton</code>):</p>

  <p>Is there a way to make the background the same?</p>
  
  <p>I'm using <code>setLookAndFeel</code> on Windows 8.</p>
