Rattle can petty blue

Adam,

I could be wrong here, but I think "Petty Blue" and B3 are actually 2 different paint codes. I always heard that petty blue was in fact a 999 code. But they are very close, and B3 blue is commonly, but mistakenly, called "Petty Blue."

Petty blue was originally a 999 special order color which later became B3 blue I believe. I will see If can can get some paint formulas.
