Stupid paint code question

My sons 65 valiant was originally "Light Blue". At some point it was painted flat black, then brought back to it's "original" color by yet another owner with a cheap single stage paint job. I have the paperwork for that work and it has the paint code as "95605" and the paint named "Light Blue". A google shows 181-95605 DuPont as having a very similar color (full disclosure, I'm colorblind). 181-95605 has a Chrysler paint code of DT8209, where as Chrysler's code for "Light Blue" in 1965 appears to be DT3876. The DuPont code for DT3876 is 93-97385.... Ugh...

Anyway, have I mentioned I'm colorblind? Does it seem like the body shop just did a color chip match and came up with a different paint?

The reason I care about this is we're replacing the windshield and need to touch up the frame and some other spots. I'd like to, for now, just get a spray bomb (don't throw anything) mixed up for this.

I know this is all over the place, any help would be appreciated.

Thoughts?
