Mainly H range, and yes strait from the bottle without mixes if I can find the good ref. I'm not a "real colour fanatic" first in the combat conditions the colors could vary from an aircraft to another and second who can say "thi is the real color that aircraft was paint with " .Do you mean the C or H range? Are the RLM colours you used on the Dora or on this 109 straight from Gunze
And When I paint I like to have some subtle shade change, I often add lighter or darker color in the main color, sprayed randomly, and finally some last coat of the base color to egalize the tone, it's really a matter of feeling.
