I think that the problem with the two greens that Art Gregory tried on the car, were the correct named colors, but the wrong colors for the car. By that, I mean that the name of the color is the same, but there can be many shades and variations of the color that use that name. I found this was the case when researching Bolero Red... It varied from a bright red to almost a maroon. You need to look at what was originally on the car, but sanding down to the original color, and then trying to duplicate that color if possible. There is more to a color than just the name...
