Factory Screw Up On Paint ????

My dart paint code is B7 dark blue. But the jambs, trunk, floor, etc are all light blue like B5. The car body was repainted at some point in a single stage dark blue. I'm guessing that the bodyshop read the EB7 code on the tag, mixed it up and sprayed it before they realized that the car was actually a lighter B5.

I happen to prefer the B5 blue. So that's what its getting painted.
