I don't think there is. Reason being, scale effect color is highly controversial. I don't believe in it for the following reasons:
- Pigment ground to scale fineness, regardless of it's original color would be dark gray to black.
- Pigment viewed at 800X is the same color as when viewed with the naked eye.
- Surface microtexture and the source of light are critical to what the eye and brain perceive as a given color. If you make two paints with identical pigment in identical amounts, but one is gloss and the other is flat, they will look like different colors, especially to the untrained eye.
As for my bona fides (mentioned because you are new here): I was a paint formulator chemist and paint technologist, and a microscopist. I've worked in or with the field of coatings technology all my professional life. The three items I mentioned, above are all from direct experience as well as theory.
That being said, all paint fades with time and exposure. Some paints change color due to changes in the binder and/or the pigment. So unless your ship is just out of the yard, the paints should be faded—and some may be very different than originally.
Bottom line: If it looks "right" to you, it is.
