You can try what I did, paint the center portion of the bar black. I had the best results when I scuffed up the area to be painted with some fine sandpaper, degreased it, shot a coat of primer, and then finished it off with a couple of light coats of paint. Make sure you let it cure out completely, otherwise it will tend to scratch off easily. Once it had cured, (2-3 days if I recall) I mounted it up and it looked great.
The first attempt was just shooting some paint and mounting it as soon as it was dry. Paint was still somewhat 'delicate', hence the advice to let it cure for a couple of days to fully harden
