Fiat CR.42 Italian air force 1941.
All types of Italan aeroplanes both fighters & bombers were camouflaged with irregular patches of brown and terra-cotta against a light green background on the upper surfaces,the green portion covered aprox one third of the available area and the other colours in roughly equal proportions,the undersides were usually painted either a sandy brown or a dull silver finish.In most cases a white band encircled the rear fuselage,this formed a suitable canvas for the squadron number which was painted in black,good examples of this scheme can be found on the beautiful Macchi C.202 Saetta fighter.
The Fiat CR.42 shown above has a salmon underside which was sometimes used on this type of machine.
