Hi Dave,
Thanks for sharing that. I'll plug one more variable into the equation:
The 5-NG that we produce is the final version of that color, introduced in late 1943. There were at least two earlier, official, dark greens.
In 1942 the USN introduced their first series of greens & browns--Brown 1A through 4A and Green 1A through 4A. Green 1A was a very dark Olive Green, in the neighborhood of FS 34064. I'm not sure off the top of my head whether these paints were made available to forces afloat pre-mixed, or were mixed from tinting pastes; I think they were pre-mixed at Mare Island and Norfolk USN paint factories.
In early 1943 those colors were dropped and replaced by 4 greens--5-HG Haze Green, 5-OG Ocean Green, 5-NG Navy Green, and 20-G Deck Green--which were mixed using 5-GTM Tinting Paste and 5-U White. Those colors apparently proved a bit too bright in use, and in late 1943 the 5-GTM Tinting Paste was revised to a more olive green hue, resulting in 5 new revised olive greens with 5-PG Pale Green and 5-LG Light Green being the newcomers.
In 1944 the USN revised things again for the amphibious and PT forces, with the new colors being #1 Green, #2 Green, #3 Green, and #4 Brown.
I strongly suspect that the color in question may have been the 1942 Green 1A. If you have access to a set of FS chips you'll see what I mean when you look at 34064. If anyone wants an accurate look at all of these colors, order the USN Set 2 paint chips from Randy Short at http://www.shipcamouflage.com.
We also have MTB Green and Tropical Green available, as well as #1 Green, #2 Green, #3 Green, and #4 Brown.
Cheers,
