I compared my listings of GTO and Firebird (not counting Judges or TA's) and noticed some interesting similarities and differences. First number is Firebird percentage and second is GTO:

Color Fbird GTO
Starlight Black 1.2% 4.4%
Mayfair Maize 0.6% 5.4%
Cameo White 8.0% 4.5%
Liberty Blue 1.2% 9.2%
Matador Red 10.4% 9.9%
Warwick Blue 6.7% 6.0%
Crystal Turquoise 1.2% 5.0%
Midnight Green 5.5% 8.3%
Limelight Green 8.0% 8.9%
Expresso Brown 3.7% 5.2%
Champagne 3.1% 1.0%
Antique Gold 4.9% 6.1%
Burgundy 3.1% 3.1%
Palladium Silver 5.5% 5.2%
Carousel Red 14.1% 2.3%
Verdoro Green 5.5% 12.7%
Goldenrod Yellow 6.7% 0.3%
Windward Blue 9.2% 1.2%

Note that Carousel Red was a standard color on Firebird but was extra cost on GTO and not even offered half the year. Also note that there are quite a bit less non TA Firebirds in the listing (163) versus the non Judge GTO's (609).

The totals don't quite add up to 100% because of the occasional document that has an illegible paint code.
