Engine compartment color

I understand that Mopars are suppose to be engine color but is that hold true for the outer fender apron area. For the engine bay on my duster is body color the outer area inside the fender area is black. My intentions is not to make a show car, but a nice restoration and under coat for the northwest weather..

My dart has the original paint and there is zero black on the car besides the undercarriage. Under the hood is all body color and even inside the wheel wells.
