Since its debut in Horizon 4, the Challenger SRT Demon’s factory colours all have the top of the car painted matte black despite the car being available without the black top. Although the black top can be repainted to match the rest of the body (unlike the Camaro ZL1 1LE), the front splitter, edging around the grill and hood scoop, side skirts and the rear spoiler were lumped into the same paint group meaning those parts of the car will match the top.
An ideal solution would be to add a new third advanced paint group for the splitter, edging around the grill and hood scoop, the side skirts and the rear spoiler like in the below pic to allow for the top to be repainted separately and then add the non-black top factory colour options to the Manufacturer Colours menu.
