The order rescinding the two-tone dunkelgrau / dunkelbraun paint scheme was issued in June, 1940, so you are well past that, therefore, overall dunkelgrau would be fine. The switch to dunkelgelb base coat didn't occur until Feb. 18, 1943.
Some vehicles send to southern Russia were finished in two-tone "Tropen scheme" (2/3 RAL 8020, 1/3 RAL 7027) in 1942, so this is possible, depending on your vehicle type, unit and/or location. This would need to be researched further to insure your particular vehicle type was finished in this manner, I can't say for sure off the top of my head...
The two-tone green over grey scheme is not an official paint scheme, but B/W photos seem to indicate this probably occured, possibly with either Luftwaffe or captured Russian paint stocks, this is still being debated ... AFAIK, no color photos of this scheme are known to exist.
