It’s a mixture of green and black, and will only closely match the FS number freshly painted. It tends to fade to different colors and will vary from forest green to a black. It is also very “rough” and scuffs easily. Camera film has a problem duplicating it as the IR qualities drive film and some digitals nuts.
The object of the paint it to reduce/break up the IR signature of the aircraft and it does a good job of it.
You will go nuts trying to match, so try for a ballpark mix.
The cockpit interior is usually painted “Aircraft Interior Black” on tactical aircraft that have NVG capability, 4/1 mix of flat black to flat white gets it nicely - the entire cockpit is this color. The cabin area is DGG, Dark Gull Gray FS 36231. Prior to the NVG mod Army Helo cockpits were DGG.
