I went to Hobby Lobby, the hobbist chain store, and bought some small artist brushes and two small containers of metallic paint (white and fire-engine red). In front, I painted the ramp up to the top, red, covering all the horizontal surface. In back, I painted the vertical posts white, covering all the vertical surface, and connected the posts across the bottom to form a U.
Total cost: about $10, and the results were spectacular. Acquiring a sight-picture was faster than ever, and groups tightened up a good bit.
