Hmm. . . I had always understood that Pantone was a system of being able to reproduce specific colors, not the colors themselves. Sort of like the FS numbers used when referencing military colors.
As far as seeing the Hero, I certainly agree that photos -vs- eyeballs will give a different "reading." I got to see it up close years ago at the very first MoM display at the Smithsonian, but it was before I really got involved in prop reproductions, and I didn't have anything to compare it with to say what paints on a color list looked OK and what looked wrong.
I love talking colors, and I think I share in most members' desire to be as accurate as possible!
