Very interesting comments on the difference of the same color name by Cadillac (Colonial Yellow). I have another question along the same lines:
I own a 1939 LaSalle Convertible (Oxblood Maroon Metallic). In comparing with other cars, first noticed a cover article in the July-August issue of "Antique Automobile" (AACA publication). There is a beautiful 1938 Cadillac convertible pictured on the cover and in the article and the color is Oxblood Maroon. The color of my car compares very closely with this color. I called the body shop that painted the above car and they confirmed it was "Oxblood Maroon" and gave me the Martin Senour Formula Number. In our conversation, they mentioned that some colors will vary, as the original paint was lacquer and most of the newer paints are base-coat clear-coat, which was what they used. They also mentioned that the colors can vary somewhat from one paint manufacturer to another.
At Hershey this year, there was a nice original (older restoration) 1939 Cadillac convertible coupe and the color was exactly the same as my LaSalle. I asked the owner about the color and he said he purchased Oxblood Maroon about 20 years ago from Bill Hirsch and that it was supposed to be the correct color. I called Bill Hirsch and formulas are no longer available. At this point, felt secure that my car was painted the correct color. (According to previous owners, my car was repainted one time prior to 1983 and the paint is still in almost perfect shape, other than a few hairline cracks). You can see my car on the Picture Gallery of the CLC by clicking on LaSalle. There are 3 pictures of my car (2 exterior and 1 of the dashboard).
Last summer, I took a very good look at an older restoration of a 1940 Cadillac Series 75 Convertible Coupe with sidemounts and it was also supposed to be Oxblood Maroon. However, the color on that car was considerably darker than any of the cars mentioned above. Since I plan to repaint the car in the coming months, am wondering which color is correct? My car, the 1938 Cadillac and the 1939 Cadillac are all a beautiful metallic maroon, but this color is redder and lighter than the 1940 Cadillac. On Ebay, I saw a 1940 LaSalle (also Oxblood Maroon) and it appeared to be darker, similar to the 1940 Cadillac.
Is it possible that Cadillac changed the formulas of this color during a period from 1938 - 1940? Thanks for any input on this.
