Alright, i will post some suggestions. The long useage of this tank on all kinds of theatres means that almost everything is possible.

Thats a C version but i can image something similar for a F version aswell. The German grey - sand yellow camo pattern used in south Russia in late 1942 and early 1943 is very different from the stuff we usually see.

Finally a F version, used in Stalingrad. It features the same colours as above (German grey - sand yellow) but the pattern is very different. All those camos were applied by the crew in the field, there were no certain rules they had to stick to.

Another F version, this time the Afrika Korps camouflage. It is simply sand yellow. Some model builders get really mad on this and tell you there is only ONE right tone of sand yellow but seriously, i do not care at all about that.

Also an Afrika Korps Panzer II F, Tunesia late 1942. It features an unusual camo pattern consisting of sand yellow and green.

Typical for early German tanks, German grey over all. This is a F version, i assume somewhere in Russia 1942.
With regard to the F version thats it, the earlier variants like the A version also had a dark brown camo pattern over the German grey but i would not do that for a F version.
