What is the factory correct way two tone paint was applied to 1956 150's? I know one way was that the roof could be a separate color than the rest of the car. But I've also seen cars with the roof,trunk,1/4's, and lower doors/front fenders one color, and the tops of doors,fenders,and hood the other color. The other way I've seen them is with the roof, tops of doors/fenders, and hood one color and the rest of the car the other color. Which is correct, or are they both correct?
