What Color to Paint Demon? White or Blue?
Isn't TB3 actually Petty Blue??
Mopar sort of marketed it that way. There was a code 99 paint in 1966 that I saw sprayed on a few Plymouth Satelites that was a similar shade. I had owned a TB3 painted 72 Demon striped like my current car. I thought it was a little on the light side compared to what I saw in magazines.
I had read letters in car mags that debated whether J or TB3 was closer. When I learned I would be travelling near Randleman, NC, I went to my local paint shop and got a sample of each sprayed on an identically prepared piece of metal. I visited a little museum at the shop and compared my samples with the Superbird. The J was closest IMO. That was why I chose the J code. I never asked my current PPG vendor for a current sample of TB3 using the current formula that they use.
Since then I have learned that automotive coatings (paint) are colored by various pigments. (The A4 silver blended by the "numbers" for my '66 Dart GT used 8 pigments, looked green, and adequately matched some unmolested original paint that I found on the car.) It is possible to blend pigments for the color desired and get different results each time. This is due to variations in dye lots. That said, even if TB3 and J use different pigment combinations, due to dye lot variance it is entirely possible for them to be indistinguishable from each other in the same light, on identically prepared surfaces using the naked human eye to make the assessment.
As a result of my experience, I do not trust my eyes or brain to remember colors for matching purposes. What ever color the OP decides to use, I advise that he purchase an additional quart or two blended from the same pigments at the time, and by the same person and equipment, the mix for the car is blended. Even primary colors, or non-colors, can turn out different.
