Color the original paint
I like the original color whether, black, grey, green. Just pull up the colors of the 1948 Chevrolet. The marketing at GM spent alot of apeal with the body shapes. When I decided on my car based on some fleck under the mounting on the door. So I painted it as it came original, I did not know how it would look, my wife saw it and said, that is the perfect color. I would never change the color.
People remember those cars with their young days. That is my opinion.
