I find the premise of this question a mite curious in that, given the purely subjective and personal nature of choosing a color, it would never occur to me to ask anyone else which color I might opt for(excepting my wife, of course
). And I wouldn't choose a color based on how well it hides dirt-it's still dirty, no matter how well the dirt keeps hidden.
Buy the color you
like-who cares what anyone else likes or wants. Let them choose for themselves when buying their
truck; not yours. It's going to be your truck and one that only you'll have to look at in the next few years.
Probably a moot point at this point in time as it seems that the op has already made his decision. Good luck with your new truck!
P.S. You really should have picked "Deep Cherry Red Chrystal Pearl" (aka burgundy)...
