The photos in 'Brothers in Arms', by Chris Goss, the book I can't get to at the moment, show mainly heavy, wave pattern and mottle on the fuselages, often with an overspray believed to be RLM 02, and possibly RLM 75, with wings also in wave patterns, similar in some way to RAF pattern, not the 'splinter' as normally seen.
The 'Pik As' was reinstated around November 1940, although at least one photo shows this being in place as early as late August/ early September 1940, possibly earlier.
Main colours seemed to vary, with 71/02 and what is believed to be locally mixed greys, possibly the forerunner of the 'official' 74/75/76 also being used.
