I think what you're seeing on the interior door panels and bucket seat shells, is the dye that mother mopar used to color the interiors. For some reason, chrysler would simply use a dye of the desired color, to make matching color door panels, consoles, ect.,ect. Back in the day, I owned several challengers with color matching interiors, the one that I remember the most, was a burnt orange interior that showed green everywhere that I rested my arms while sitting in the car. I assume that assy. line shortages or cost cutting measures were the reason.
