You're saying you are going to have black door panels and dash pad and seat on light blue sheet metal? You may want to photoshop that, or see if anyone here has that combo. I've seen a dark blue with black, and it didn't look too good honestly. Naturally, beauty is in the eye of the beer holder, and that is one man's opinion, but if you can get a picture of someone's, at least you'd have a good idea.
My first truck was blue on blue and I loved it. Not a day goes by that I don't think of that truck.
But, slowly, this one ton is becoming more of a truck than that one was... it was just better looking than this one is, and that can go a long way sometimes.
