You can also paint a simpler North African scheme without the RLM 80 Olive Green mottle. The Bf-109F-4/Trop and some Me-110s had RLM 79 Sand Yellow on the top surfaces half way down the sides of the fuselage with the under sides in RLM 78 Light Blue. This is about the easiest operational Luftwaffe paint scheme and really looks good with the white wing tip and nose trim.
Simpler yet, some their pre-war operational and prototype aircraft were painted in overall RLM 63 Light Gray/Green-gray.
Good luck,
Pete
