JProgressBar background colour

Question

I am trying to set the foreground colour of progress bars to green, and the background colour to yellow, I am doing the following

  JProgressBar pb = new JProgressBar(0, 100);
  pb.setBackground(Color.YELLOW);
  pb.setBorder(BorderFactory.createEmptyBorder(1, 1, 1, 1));
  pb.setForeground(Color.GREEN.darker());
  pb.setOpaque(true);
  pb.setStringPainted(true);
  pb.setPreferredSize(new Dimension(pb.getPreferredSize().width, 16));

I expected the bar to be yellow, instead the colour behind the bar is yellow. See below (I have tried the UIManager approach as well)

enter image description here

EDIT: It looks like it's the Windows L&F that's causing the issue

As I said I have tried the UIManager approach mentioned in that post — PDStat, Jan 30 '14 at 14:22
Then I recommend posting a full example that shows exactly what you've tried so that we can copy and paste it and run it ourselves. AKA an [SSCCE](http://sscce.org). — Kevin Workman, Jan 30 '14 at 14:28
Two approaches are suggested [here](http://stackoverflow.com/a/16625494/230513); if the former fails, try the latter. — trashgod, Jan 30 '14 at 18:41
@trashgod thanks, it looks like it's the windows L&F that is causing this so I guess using ProgressBarUI is my only option? — PDStat, Jan 31 '14 at 08:35
I like [tag:jfreechart], either stand-alone or in a custom delegate. — trashgod, Jan 31 '14 at 08:48

Unfortunately not, the yellow outline disappears in that case. I have a feeling it's something specific to using JIDE components, hmmmm – PDStat Jan 30 '14 at 15:04
