...sometimes I think we see what we want to see. Really. I've been to Jim Carters several times and each time I look at the NOS engine, still in the crate, sitting in his front room, it seems to change colors....which time, light (sunshine or "bulb" light) can change shades and I agree with who said we'd probably never know the real formula.
my opinion...
I've spent 37 years in printing/finishing/dyeing and I don't think I ever saw a "perfect" or "identical" match to the original color standard. I saw some close, but not dead on. We could make "adds" all day long and not hit the target as a dead match. Even using the sophisticated spectro's.
..and as someone suggested, the color may have had a lot to do with who had the lowest bid.....in my profession we OFTEN switched the raw color manufacturer to use a different product that may have even been more costly but supposedly better. That of course, meant we had to "reformulate" the colors!!
...but I like many of you, want the REAL DEAL which we know we will never get. But we keep hoping and where there is hope....the is hope. Oh, by the way. I still like the blue/gray!!
And thanks to all of you who contribute to make this such a nice site.
