"In 1939, as a result of ABTU's initiative, NIIIT developed a deforming colour scheme for tanks and armoured cars.
Between August 15th and 29th, 1939, ABTU's proving grounds (Kubinka station) performed research on deforming large-spotted colour schemes of wheeled and tracked vehicles. ABTU Chief, Hero of the Soviet Union, Colonel-General of the tank forces comrade Pavlov and IU KA Chief, Major-General comrade Mihailin took part in the trials.
As a result of the trials, it was determined that it is beneficial to replace the olive drab factory paint with a multi-coloured deforming paint scheme. The report with blueprints and photographs was sent to ABTU on August 11th, 1939 (source #38).
NIIIT KA proposed performing field trials in 1941 and provide GABTU with results in June of this year. Currently, NIIIT is performing laboratory tests of deforming paints, in order to finally establish the patterns and composition of the paint. Trials are scheduled for May 10-25th at the ABTU proving grounds (Kubinka station). NIIIT has ordered sufficient amounts of paint for this task.

However, war does not wait politely for trials to end, and the tankers took matters into their own hands.
"From reports coming to GVIU, it can be seen that active army units apply a deforming colour scheme to their tanks and vehicle, in order to hide them more effectively. However, due to a lack of appropriate colours and poor execution reduce the effect of the paint. I think it is necessary to apply camouflage paint in factory conditions, and hurry the preparation of instructional posters.

Here's a picture of one of those custom-painted tanks. The pattern is very unusual, with tactical markings hurriedly painted over top.
Here are proper instructions for summer camouflage (for artillery):
In order to fulfil this order, the Council of People's Commissars issued order #5667 on August 7th, 1941, ordering the People's Commissar of Chemical Production to ship 6K and 7K paint using part of the budget for 4BO paint.
It is imperative that camouflage paint be applied immediately, as soon as paint and instructions are received.
Report on delays in this transition, and report as soon as you complete transition to this new camouflage scheme.

The colours were defined as follows (from Kolomiets and Moshanskiy, Camouflage of Red Army Tanks 1930-1945):
- "Green - 4BO (medium colour) works with all green vegetation backgrounds, and is the main, dominant colour. This colour covers 45-55% of the surface area of the object.
- Yellow-earth - 7K works with bare earth backgrounds (plowed soil, roads, rock slides, etc). This colour covers 15-30% of the surface area of the object.
- Dark brown - 6K works with dark spots on various backgrounds and with tree trunks. This colour covers 15-30% of the surface area of the object.
- Spots must imitate natural shapes, must have wobbly contours, and must vary in shape and size.
- Spots must be arranged in such a way as to alter the appearance of the object as much as possible. Recognizable parts of the object, such as straight lines and angles, shields, gun barrels, wheels, etc, must be painted with spots of various colours. The direction of elongated spots must not be parallel to the outline of the object, and must intersect with it at various angles. Spots of one colour and similar size should not be placed symmetrically. Spots may be enclosed in one part of the object, or cut off by the outline of the object. "Open" spots must "travel" on to adjacent surfaces, i.e. be painted on at least two surfaces. Angles that are sticking out must be painted in predominately dark colours. The top of an angle must not coincide with the center of a spot. Permanently shaded areas of the object must have highly contrasting yellow and brown spots.
- As a general rule, using stencils is unacceptable.
The spot locations must vary in accordance with the above rules. Alternatively, it is necessary to vary the colours in the included drawings, replacing all or some of the yellow spots with brown, and brown spots with yellow.
The book also includes instructions. The spots must be first outlined in chalk, and labelled with a letter signifying the colour. In the event that the tank is already painted green, only non-green spots are labelled and painted. When converting summer camouflage to winter camouflage, paint over the green spots with solid white, and over the yellow and brown spots with a hashed pattern. Depending on how open the terrain is, increase or decrease the density of white stripes. Captured vehicles coloured in monochrome grey must be painted in the same fashion.
Unlike tanks, artillery was very commonly painted in camouflaged colours, even artillery in the Reserve of the High Command, which theoretically wouldn't have much use for it.
On camouflage of combat vehicles in winter conditions
1. Type of paint.
A chalk mixture is used in order to paint. During frost, use warm water to prepare it.
Amount: approximately 1200 kg for a two regiment tank brigade, or 5-6 kg per vehicle.
In cases where there is not enough chalk, it is possible to use slaked lime. Lumped lime is completely unsuitable for this task. Disadvantages of using lime: the paint will gradually turn brown, the lime acts as an irritant. Both types of paint can wash off, and are not resistant to snow and rain.
2. Directions on application of camouflage paint.
The order to paint is given out in the winter, right before the vehicles will be used. The order is given by the same unit that orders the use of combat vehicles.
The painting is done by the crews themselves, as close as possible to headquarters (where warm water is available).
Brushes used for washing cars may be used for painting, as well as any containers (buckets, etc). The time to paint a vehicle is 2-3 hours."

The Red Army also had a large amount of unofficial winter camouflage schemes.
