All the early series production  MiG-1s and MiG-3s were painted with:

• AII green  uppersurfaces,
• light blue undersurfaces;
• six red stars (often contoured in black) on fuselage sides, wing upper and undersurfaces.
• propeller blades were left unpainted aluminium, with partially black painted rear surface, often very worn off by air abrasion.
• The pitot probe was light, probably light blue, with unpainted aluminium end.

This scheme was common for MiG-1s and early MiG-3s, till the war outbreak.
The metal surfaces (aft fuselage, horizontal tail surfaces, central wing plan) appear lighter and worner than the wooden surfaces (rear fuselage, outer wing panels); this is well visible on nearly all German photos (forthemost representing aircraft captured or wrecked during the first days of war), but not on Soviet photos (few of which represent this scheme, and they show forthemost new aircraft from the factory).
The difference between green shades on wooden and metallic surfaces is very marked in aircrafts abandoned for a long time. It was probably due to different painting techniques on separed sub-assemblies before the final assembly, that led paint on metal parts to fade quickly if exposed to the sunlight.
The green/blue demarcation line was sharp on the nose and metallic parts of the wing and tail, while it was soft on wooden parts; besides, wooden and metallic parts were painted before the final assembling, and this can be understood because demarcation lines are often discontinued on junctions.
This way to paint MiG-3s was abandoned more or less contemporarily to the war outbreak, and to the introduction of late type MiG-3.
