It would be very helpful customization wise to have colors attached to parts, because for some vehicles the 3 available color options aren't enough. The selected color would be applied to one slot and to one material for simplicity's sake, the name of the colorable material could get defined inside the jbeam for example, so say I have a part with a mesh that has 2 materials: material1 and material2, I define material1 as the colorable material, therefore when I change the color of that part it only changes the base color of material1. These could be saved inside .pc files like this: "partSlot":"part {rgb:255,255,255}", . The part selector could look like this : I see this as a way better alternative to making 10 extra skin slots that only change the base color.
