The most usual colour schemes for MiG-3 are:

• green and dark green uppersurfaces, with light blue undersurfaces; sometimes overpainted with non-standard black or sand mottles or stripes;

• green and black uppersurfaces, with light blue undersurfaces;

• green or factory green (dark blue-green, sometimes used until mid-1941) uppersurfaces, with light blue undersurfaces;

• green, dark green and black bands with light blue undersurfaces; it's not clear if these schemes are from the factory or are field repainting on a two-color base. Perhaps some squadrons received both black/green and dark green/green aircraft, and tried to standardize the camouflage by adding the missing color on each aircraft; some photos seem to show 4-color camouflage, too; we could consider the possible use of ochre too, which is difficult to distinguishable from black in b/w photos.

• white mottles over camouflaged aircraft; usually the rear fuselage, tail and wings are mottled white, while the central and forward section are not mottled. This scheme is common on LaGG-3s, too, and perhaps is so to avoid to dirty one's uniform with fresh white paint when there was no time to let it dry;

• white oversurfaces (by workshop or field painted over the standard camouflage) with light blue undersurfaces; sometimes different shades of white (or light grey) are present on the same aircraft, particularly on the removable panels that could be exchanged from one aircraft to another. The white paint wais often painted in the field, but sometimes it could be painted in the factory;

• overall white or light grey.

• the serial number on the right side of the nose (it looks black on white backgrounds, and a lighter color, perhaps red, on the camouflaged backgrounds; perhaps it's always red);
• a black line on each side of the fuselage, under the leading edge of the horizontal tail plans, perhaps to show a lifting point; not always present.

• usually blue-grey for the undercarriage legs, wheels, bays and doors; sometimes they look painted with a light color, perhaps the underside light blue or metal primier grey-green (indistinguishable in b/w photos) and dark color (probably dark green) wheel hubs;
• blue-grey for the cockpit interior, instrument panel (with black quadrants) and radio boxes, radiator cowling interior and so on; (on some photos, I think to see also all-black instrument panel, but I'm not sure);
• the propeller is usually bare alluminum, often with the rear part partially painted black (often showing alluminium patches near the extremity; on white-painted MiGs, the blades are often painted white themselves; exceptionally the blades are camouflaged.

The AII colors were standard in the years 1940-41, and widely used in the following years too, even when AMT colors became standard.

Here are approximate equivalencies to many color catalogues. The color chips shown below are only generally indicative, partly by the difficulty to see screen colors and painted chips under the same light, and partly for the different visualisation of the same file on different computers and even between different programs on the same computer.

note: many of these notes are based on the previous research of Eric Pilawski. This research has given some surprising results:

• the brown color shown on many previous profiles was not produced in the USSR in 1940-41, and was not used on the MiG-3.
• the black-green shown on many profiles doesn't exist either;
• the green is not olive, but rather light and yellowish;
• the dark green appears nearly emerald green;
• the usual interior color was not light grey.
