I realize that this a recurrent question, but with the advent of the Airfix Me 262, I think pertinent.
I am having trouble with two specific colours, RLM 81 and RLM 82, as applied to Me 262 airframes late in the war, 1944/5. I have seen photos of reconditioned museum examples, and the paintwork is quite bright, especially the light green 82. I also have Ullman's treatise Luftwaffe Colours, and have referenced IPMS Stockholm.
Nothing agrees.
Is there an authoritative answer, or at least consensus, as to the hue and shade of these two colours? Can it be stated as an FS number? Is/are there commercial model paints that come close? I notice that Airfix quotes #251 for RLM 81, and #252 for RLM 82. Close?
