I am pleased with the accuracy of Tru-Color's Deep Sea Green for CNJ diesels prior to the "Austerity Green" dip paint job. We matched that color for Sunset GP7Ps. I like these so much I have them in 4 road numbers.
However, as a contrast, I also have the Williams GP9 (Actually a GP7) in CNJ and I can't complain too much about the color on it. It would be interesting to see the various CNJ "Deep Sea Greens" side by side in the same lighting. The HO locomotive in this photo is a Tenshodo that I painted myself around 1995 using Floquil Brunswick Green not knowing any better prior to the wonders of internet research.
