Special Paint

Some plants used a DuPont mixing formula to indicate special paint. Literally any color available from any auto manufacturer could be special ordered, be it a sister GM division, Ford, MoPar, etal. Listed are just some of the codes and colors I've run across. For more information visit this page. If the code begins with "926" it indicates a non-metallic color where "927" is a metallic color. As more are discovered, they'll be listed here.

DuPont Code Known Color Non-Metallic (common name)
926-98371 Light Blue (Carolina Blue) (1969, 1971 & 1972)
926-96881 Light Blue (Carolina Blue (1970)
926-99539 Orange (Similar to Pontiac Carousel Red)
926-99568 Chevrolet code 76 - 1969 Daytona Yellow
926-99616 Chevrolet code 72 - 1969 Hugger / Monaco Orange
DuPont Code Known Color Metallic (common name)
927-98457 Tricentennial Gold
927-99593 Chevrolet code 71 - 1969 LeMans Blue
927-99846 Chevrolet code 43 - 1970 Canada Citrus Green
927-99918 Aqua

Here is a 1969 paint chart showing the DuPont number under Production Code so if someone wanted a 1970-1972 in a 1969 color, the Production Code should be on the 1970-1972 trim tag.  I wish I had access to the same information for other years but this is all I have.
