They had very strict rules for how and where to paint there aircraft.
There are clear images of Graf's Grün 1. These can be found in several books, including the one I linked above. There's no need to guess or use decal sheets of other aircraft as a guide.
The mottling and some other types of paint were customized from plane to plane, but the splinter scheme was pretty much set. You have maybe 1-2 variations for every plane on the standard 2-tone splinter scheme, but it's not as individual as you make it seem. Overspraying, and whitewash, and other things go on top of the splinter, but the splinter underneath is very much similar to the plane next to it.
There was no set pattern to the mottle. The amount of mottling depend on the painter and they varied from plane to plane. If you are looking at one plane for detail and skinning another your final product will be inaccurate.
Fencer,
Just trying to get the basic colors down and understand the way the Luftwaffe did camo. Should the molting be RLM75 or RLM74?
The colors would be RLM 74 for the dark uppercoat. There are several variations of RLM 74 from a dark grey to a grey/green. Sundin (the profile in your original post) has chosen the dark grey but others have used the grey/green tone for Grün 1.
RLM 75 is the lighter of the uppercoat it can be a shade of light to medium grey.
The mottle for the most part would be a light coat of rlm 74 (same tone as the dark uppercoat) and as it fades the undercoat of rlm 76 would show through. From the images I have seen of Grün 1 there is also some RLM 75 mixed in as well
For RLM 76 my best guess would be the blue green variant of RLM 76.
As for the decal sheet you posted the wing camo pattern is accurate enough.
The lighter coat of the upper wing would be RLM 75 and the dark camo would be RLM 74 with the distinctive 'steps'.
The mottle on the decal sheet OTOH is less so. Look at the photo of Grün 1 at the top of this page:
JG 50: "Geschwader Graf"You can see splotches of RLM 74 with what appears to be lighter splotches of RLM 75.
There's plenty of room for artistic interpretation so good luck...
