Well, you certainly elicited some opinions, haha. You chose the colors well, but unfortunately a thin stripe or even a couple of them on a rig that size is like stretching a ribbon across an acre and looking for it from the air. I think you're on the right track otherwise. The original tan was not a bad call, and a gold that approximates that same color is a good idea. Putting a vinyl center band of tan or gold would be the thing that really sets it off. There's probably a reason why GM used that big five-stripe to separate the colors. Anything else was just too subtle at the time. Contrast will help get you there if you want to go with a narrow stripe. White and the aforementioned yellow or orange are probably the only ones bright enough. White is safe, yellow and orange would probably need a test run.
