Hi all,
RLM 83 was NOT a green but was a Dunkelblau (Dark blue) used only during 1944 in the Mediterranean aera. It was to be used with maritime colors such as RLM 72 or 73.
The green 83 was a convenient reference created by historians who discovered a variation of... RLM 82.
RLM 99 included all colors of varnishes, putties, etc. and ran from dark red to greenish yellow or very light greys. In the above list, yellow green is only for varnishes protecting metal sheets against corrosion.
