You are quite correct, that PPG DBU/DBI color looks altogether different depending on
what light source you viewing in, what angle you see it from, what the surface finish and
texture looks like.
I can lay the sample plate that I have of the 27467 next to the original color that’s on the
truck and can make it look exactly like it simply by changing the angle of the plate or by
moving it into the sunlight or by using a CFL, incandescent, or LED light source.
The same set of problems apply to all paints, another good example is the gray engine
color used on the AD engines for decades. In some light the paint on my engine looks
dark charcoal gray and in other light it almost looks like Rustoleum smoke gray.

And it is impossible for judges to tell the exact color also, which means that we simply
need to choose a shade that is close and go with it, who’s gonna know.

What does stick out like a sore thumb is when the interior is painted the body color or
black or something totally off shade from the original colors.

One other thing on the manufacturer of the paints. As far as I know Ditzler (now PPG)
was a refinish supplier and I’ve seen it in print that the AD’s were supplied paint by
DuPont and that it was Dulux enamel on the Commercial vehicles. I’ve never seen a
DuPont offset color for the interiors.
