Hi...
The thumbnail you provide seems a little 'bright' in its reproduction, but I would suggest the greens are perhaps RLM70/71 (schwarzgrün and dunkelgrün respectively). Undersurfaces would be RLM 65 hellblau, with yellow RLM04 cowling, wingtips and fuselage band and white RLM21 spinner, probably with an RLM70 backplate. The green of the 'Grünherz' emblem would have been RLM25.
A few things to bear in mind: firstly, the profile you provide is of a machine from JG54, who were specialists in experimenting with unorthodox and non-standard colour scheme applications; secondly, I suspect that one of the greens could actually have been RLM02 'RLM Grau', or a mixed shade incorporating that colour; also note that some RLM shades did change during the lifetime of the Luftwaffe, although they retained their number - for example, the 1938 shade of RLM65 would be different from the 1941-onwards shade.
If you're able to obtain copies, then I personally think that
Luftwaffe Fighter Aircraft in Profile and its companion volume
More Luftwaffe Fighter Aircraft in Profile by Sundin and Bergstrom (Schiffer), give an excellent impression of fighter colour schemes. The first thing I noticed about the second volume was the 'toning down' of colours for scale effect on the profiles, and although both books are first class, I really think the second volume has captured the colour tones very accurately... just a personal opinion, though...
. Some of these authors' material has reached the inernet, I believe. I can't remember where exactly I've seen them, but I'm sure you could 'Google' your way to finding them.
In case you're interested in obtaining them, the ISBNs are: 0-7643-0291-4 and 0-7643-1559-5.
