Overall color of USMC helicopters from 1977 until 1985.
One of the colors used in the wraparound scheme applied to the USMC helicopters from 1985 until 1993.
A good match to RAL 6003 (modern RAL 840 HR), one of the camouflage colors used in the German Luftwaffe’s Norm 83 wraparound scheme (Tornado, F-104G, RF-4E, Alpha Jet etc.) and Heeresfliegertruppe’s (German Army Aviation Corps) Norm 84 scheme (UH-1D, CH-53G) employed in the 1980s-1990s.
