From what I can find, there seems to have been at least two distinct camouflage schemes applied the this aircraft. The most common appears to be that shown in the Krakau museum.

It's probably a light/medium green and Prussian blue in a two-tone pattern, and over this is "splattered" dull yellow and medium/dark green.
The second scheme is what I've seen called a "scrumble" of four or five colors.

It appears to be overlapping blotches applied with a rag or a sponge, very probably in the same colors as the lozenge fabric on the wings.
There's a better shot of this somewhere on the 'net, but if I bookmarked it I've lost it somewhere. I'll look some more.
