body: <p>How to change the color of the actual box of a <code>JCheckBox</code>?</p>
  
  <p>If I change the background color, it affects the color behind the text and checkbox, but not the color of the box itself.</p>
  
  <p>If I change the foreground color, only the text's color is affected.</p>
  
  <p>I can't find any other color properties.</p>
  
  <p>I just want a simple <code>JCheckBox</code>, with one color, which is changes when I check it.</p>
