Anyone know the official name of the pale yellow paint, or the gold/green vinyl roof, or the light brown interior on a 1981 LeSabre Limited 4-dr?

Ford, the color names are in the GM Standard Parts Book under paint. Some of the names are on the fanciful side, and it is not clear what color they are close to. Probably we need to look at the color code numbers on the second line of the body number plate. The first number is the interior trim code. The second is the lower body color. The third is the fabric top color.

As a guess, the paint is Beige (59), the vinyl top is Light Jadestone Iridescent (45T), and the interior is Medium Doeskin (64). We can look up the code numbers if they are something else.
