I am restoring a 1931 Cabriolet in the colors you are looking for. Unfortunately, you are going to find that no one knows exactly what the color looked like at production, especially the greens. To compound the problem, the paints are different today than what they were just a few years ago let alone going back to the Model A era. With the new paint systems comes a whole new set of paint codes. The old codes for the most part do not equate to todays paints. I finally gave up trying to get a paint dealer (PPG) to mix me something and went to TCP Paints and purchased the base colors in quarts, in acrylic urethane (blue, yellow, green, black and white) and experimented with small amounts until I arrived at the color I wanted. It was easy. I mixed the Kewannee color (the lighter color) first and then added the color black until I had the Elkpointe color. I'm very happy with the results and far cheaper than what the PPG paint would have cost me. Good luck, Ed
