Bish,
Have you thought about painting it Red and white, to match the truck (Ie red below the roofline, white above)? Adrian's Cage is red on a Red truck, and blends in quite nicely with the rest of the car - you know it's there, but it's not completely in your Face.
Both colours are available as Smoothrite, so whilst they might not be the most resilient, they can be touched up easily and cheaply.
