The build sheets had to specify the color of every part of the car. This was fairly complicated on some cars. The colors of some items were spelled out on the top part of the build sheet, and others were shown on the lower part using RPO codes. In the RPO section, the color codes are all two digits, and they would be followed by a one-digit suffix for a part of the car. For example, 55P denotes gold wheels. "55" means gold, while "P" means wheels.
For example, my 1977 car is black and has buckskin tan interior. I have gold wheels. Out of 4 possible color codes on my build sheet, I have just two: 64N (for buckskin seats etc) and 64X (for saddle dash, carpet, etc.). My build sheet says EXT PT BLACK instead of having a 19L. Brian's 1978 car has 55P for gold wheels, where mine does not. His car also has 50L for paint instead of EXT PT. Our cars have color-coordinated seat belts, but they didn't start using a color code for that until 1979.
|Want a fat example? A 10th anniversary Trans Am (TATA) has 152 ( silver leather interior), 15X (silver dash, carpet, etc.), 159 (silver seat belts), 15L (silver paint), and 16P (gray wheels).|
|The 1980 Turbo Pace Car puts it over the top with six codes: 12C (weird combination leather/cloth multicolored seat), 16X (charcoal dash,carpet,etc), 11L (white paint), 11P (white wheels), 16M (charcoal accent paint), and probably 169 (charcoal seat belts). The seat belts were multicolored in this car, and I can see the 9 but I can't see the color code. In additional to all this, it has a giant 11 like the giant Y82 back on the buildsheet bingo page.|
|The Nascar is a lot like the Indy, but has a U, instead of an M, for the upper 2-tone paint scheme. This the only type of car in all my build sheets to use a "U".|
The idea in 1976-78, I think, was that the accent color matched a paint color for that year. Some cars would have been made for dealer stock featuring this scheme, which looked pretty impressive in the showroom. You'll see what I mean, I hope.
I've only seen this interior once. This very original 1976 Formula belongs to Tim Cole. It features the white with lime interior with the optional lime seatbelts! The exterior even has the lime over-the-roof stripe. It's certainly unique. I photographed it at the 2006 STARS show.
I have only seen a couple of these cars, both on ebay, and both times the paint on the car was aqua to match the interior. I wish I had kept pictures of this car, showing the exterior also.
Ember is a color that you can't guess from its name. Luckily, it was offered in paint, so we know it's a bronze color. I've never seen this interior, but it must look very similar to this picture, which is actually a 1979.
In 1979, GM offered camel tan paint (Pontiac called it "Sierra Copper"). While the camel tan interior pieces were quite "normal", they still had the same effect when used as "colored appointments" in a camel tan car.
This isn't the real Ember, however.
The 1979 Firebirds didn't offer white interior any more. They called it "oyster" instead, and it has a little silvery tint to it.
Pontiac was getting lazy! This scheme was offered two years, and it was made using the plastic parts from 1979 and 80 pace cars, so no special colored parts were needed. It looks like an Indy Pace Car interior with regular white seats.
In both 79 and 80, you could make yourself a "poor man's Pace Car" with white or silver Trans Ams being offered. There are a lot of these around. As you can see from these photos, these schemes were available in standard and deluxe interior.
