Digital Colour Chips, VVS, 1935-47

Update 2021

The following table is a digital representation of the various aviation lacquers of the 1930-50 period. We would like to respond to the very many requests for such a table on the site. However, allow us to express an ENORMOUS caveat when examining this chart-- it is intended for representative purposes ONLY. It is not currently possible to guarantee the exact colour or shade of anything drawn on a computer monitor. These samples are to be regarded only as a general familiarization, particularly for those new to the subject, and should not be accepted 'as such' with the value shown on your screen.

Here is an updated page showing the latest in VVS colour chip research*. The known lacquers are now shown by family, and include some newly discovered paints. This update incorporates new material published by reseacher Mikhail Orlov.

A-x Family Primers for internal use

These primers were intended for use in the cockpit and engine bay. Both pipes/ducting/tubes and the corresponding flight instruments or gauges were colour coded as noted below. The 'F' designation indicated a formulation of the lacquer which could solve in alcohol. The finish upon application was matte.

A-6, A-6F 'yellow'

(fuel lines & system)

A-12 'black'

(air system)

A-7, A-7F 'green'

(cooling system)

A-13, A-13F 'red'

(anti-fire system)

A-8, A-8F 'brown'

(oil system)

A-14, A-14F 'steel'

(cockpit finish)

A-9, A-9F 'dark blue'

(supercharger system)

A-10, A-10F 'blue'

(oxygen system)

ALG Family Primers for internal or external use

These paints were durable multi-purpose surface primers which could be sanded when dry. The finish upon application was matte.


ALG-5 (1)
ALG-2 (described as 'yellow') ?
138A (2)
1. After 1943 the NKAP recommended ALG-5 as the preferred cockpit finish for all aircraft.
2. Primer 138A is newly described by researcher Orlov. Its appearance is known only from the corroded chips of the 1948 Albom Nakrosok, and therefore the author regards the appearance as entirely unreliable. No sample of a brick red coloured primer such as this has yet been found on a period airframe to the author's knowledge.

AEh-x Family Lacquers for external use

These were cellulose acetate finishes with a high potassium content to reduce flammability. They were most suitable for fabric surfaces, either as a dope or surface covering. The finish upon application was semi-gloss. AEh lacquers could absolutely not be applied with a brush and must have been mixed with a hardener and sprayed onto the surface.

AEh-4 'blue'

AEh-10 'dark grey'
AEh-7 ("protective", unknown, possibly green)
AEh-11 'black'

AEh-8 'grey' (2)

AEh-14 'light blue'

AEh-9 'light grey'

AEh-15 'dark green' (1)
1. AEh-15 was issued in a full gloss finish only. Both VIAM and the NKAP strongly recommended the use of this paint for hydroplane aviation to cover the hull surfaces, inside and out.
2. Lacquer AEh-8 is shown in the 1948 Albom Nakrasok as a bright aluminium finish. Its name is indeed given as "AEh-8 Aluminium". AEh-8 is not described this way in documents prior to 1948-- it is specifically called "Grey". The author is certain that the appearance of AEh-8 was changed after the war and by the time of inclusion in the Albom. Many samples exist of AEh-8 from SBs in Spain and Finland; all are grey in colour as shown in the relevant chip above.

AII (A2) Family Lacquers for external use

These were cellulose acetate butyrate lacquers with a rather complex chemistry (possibly including zinc chloride, which is mentioned periodically). These finishes were renown for their superior durability and reduced flammability. They were most suitable for wooden or fabric surfaces, either as a dope or surface covering, and could be used over metal surfaces (in which case priming with ALG was recommended).  The finish upon application was satin.

AII Light Blue (1)

AII Brown

AII Green  (7)

AII Red (5)
? AII Light Brown (or Sand Brown) (2)

AII White (5)

AII Dark Green (3)

AII Black

AII Aluminium (4)
AII Light Grey (6)
1. The NKAP recommended the use of AII Lt Blue as a cockpit finish, "where desirable". The archaeological record shows that this was done often during 1938-41, and in particular aircraft built at Factory No 1 show the wide-spread use of this paint as an over-all cockpit finish.
2. AII Lt Brown is also called "Sand Brown" (pesochnii) in various documents; it is unclear which was the preferred nomenclature. Alas, the single example I had of this paint turned out-- following chemical tests-- to be a highly contaminated sample of ALG-1. As a result, I do not currently know the correct appearance of this colour.
3. The camouflage evaluation documents produced by the Scientific-Test Institute of Technical Engineering (NIIIT), from which we obtain the description of this paint, are rather confusing. A dark green, black green and black colour are all mentioned, and in such a way that it quite unclear whether the documents are referencing one paint, two or three?
4. AII Aluminium was the standard dope used on fabric covered control surfaces before, right through, and even after the war. It was equally widely used over other fabric areas, and the Government indicated that this paint could be used in cockpit interiors. Remarkably, Polikarpov biplanes built in Moscow show evidence of this unusual finish. The use of 'satin' to describe this paint's surface is meaningless-- the finish was so bright and reflective that even "extra gloss" is inadequate to describe it.
5. AII Red and, later, White were the standard colours employed for Soviet national star insignia.
6. Reference to this finish was only recently uncovered, and its appearance is unknown.
7. The nomenclature AII Green is now confirmed beyond reasonable doubt. However, this paint seems to have had an inordinate number of descriptive names such as Yellow-Green, Green-Protective and Green to name only a few.

Researcher Orlov has added many descriptive names to the AII paint system. These indeed can be seen in period documents, but in a somewhat haphazard manner. If we compare the material from the NIIIT to that used by the NKAP, UVVS and other State organs, the descriptive names do not match. Mr Orlov has located the descriptive names "AII Tobacco", "AII Cream", "AII Light Green", "AII Orange" and repeats the often quoted "AII Protective". This meaninmg is now disproven. It seems highly probable that these descriptive names were just that: descriptive. The exact description used might therefore have changed over time, or even might have been informal. For example, surely AII Pesochnii (Light Brown) was the same paint as AII Cream. There was, after all, only one such colour in the AII range. Moreover, of what possible use was an orange colour for external camouflage? And what colour is "tobacco", exactly? A sort-of red brown... if so, is this AII Brown from the NIIIT?

The most debated colour for years has been AII Green. However, this lacquer has now been found in many T.O. and Remont, all under the correct designation "AIIZ". All AII lacquers were officially noted in this way, with the formula being followed by the colour (without brackets): АIIСГ,
АIIАЛ, АIIС, АIIТб, АIIКр, АIIЧ, АIIТЗ, АIIКор, АIIБ, and so forth; AII Green being, АIIЗ. The "Z" was suggested to have meant zashitnii (protective), but this was not so. The last cipher was always the colour; no exceptions. The wording in many technical documents also makes this clear, such as "... two coats of protective aerolacquer of the type AIIZ should be applied..." 'Protective aerolacquer of the type AII Protective!?' No.

AMT-x Family Lacquers for external use

AMT were organic (linseed based) alkyd finishes with an iron-calcium catalyst. They were suitable for use over any material, and even without the employment of a surface primer. The finish upon application was satin, although with exposure to the elements that became semi-matte fairly quickly. Upon very close inspection, this family of paint appears to be irregular and slightly "bumpy", contributing to its matte appearance.

AMT-4 'green'

AMT-12 'dark grey'

AMT-6 'black

AMT-1 'brown' (1)

AMT-7 'blue'

AMT-1 'brown' (alternate version)

AMT-11 'grey-blue'

AMT-16 'blue-grey'
1. It is not known why AMT-1 appeared in two distinct colour shades. Pe-2 p/n 341-23 wore both versions, the darker of which had been partly applied over the lighter in a manner so as to replicate the camouflage pattern following field work.

Ax-m Family Lacquers for external use

These paints were alkyd enamel finishes specifically intended for use on metal surfaces, with or without priming. Despite having been ordered in 1941 along with AMT paints, there is no physical evidence of the use of Ax-m lacquers until the autumn of 1943, following the issue of the NKAP's new painting recommendations.The finish upon application was satin.

A-21m 'light brown' (1)

A-32m 'dark grey'

A-24m 'green'
A-26m 'black' (3)

A-28m 'blue' (2)

1. The official use of light brown to describe this colour is inexplicable.
2. There is no known physical evidence showing the use of A-28m during the GPW. All wartime airframes which have been found to date wearing Ax-m finishes on the upper surfaces were painted with AMT-7 Blue unders. It is currently thought that A-28m came into service use during 1947, and is confirmed from 1948. The updated colour swatch is based upon VIAM's documented comments regarding the 'greenish' tint to the finish (and the causes of this), and from new samples taken from un-restored Il-10 airframes in the Chinese AF Museum collection.
3. A-26m Black was ordered in 1941, but no evidence exists for its use as a camouflage finish and no samples of it are known. The Album Vozdushnyikh Vintov 1943 (Catalogue of Aviation Propellers) suggests its use on various propellers, from which of course archaeological paint samples are not routinely collected!

Other Various Finishes With Aviation Use

A few other paints in use on VVS aircraft from the 1930s.

MK-6, MK-6F 'noch' (1)

AE-10 'grey'

MK-7, MK-7F 'winter' (2)

3B 'protective'

AE-8 'gloss white'

Common Industrial Primer (nomenclature unknown) (3)
1. MK-6 night was developed for use on long-range aviation (ADD) bombers. It was found to cause inordinate drag and was replaced by AMT-6 from 1943. The 'F' version was alcohol soluble.
2. MK-7 was the standard white finish adopted so enthusiastically during the first winter (1941-42) of the war. Disastrously, it was found to cause excessive drag, and was gradually abandoned during 1942. The 'F' version was alcohol soluble.
3. Not a single paint, but rather a species of commonly used industrial primers with similar chemistry and colouration. These were widely observed on various sub-components delivered to aviation factories: steel tubes, pressed sheet items like instrument panels, armour pieces, mounting brackets and such like.

The Number Colours

During the period roughly from 1935 to 1939, the Soviet government decided that it would like to "standardise" aircraft colouration at the various factories. This was a rather ironic pronouncement from a collection of Ministries who could not help but to stick their respective oars into any such discussion and authorise or deny the use of outdated paints; but such is the nature of large bureaucracies. The idea seems to have been to identify ten, or so, colours as a standard palette, whereupon the government could simply refer to "colour # 3" and be sure that a yellow-green surface finish would result.

But, however often one encounters these numbered colours, I could not figure out to which colour these numbers referred. It was a vexation. Happily, researcher S Kuznetsov has found out for us; and we must all be grateful at long last for that discovery. Therefore, the colour numbers are described according to the following chart.

Lacquer # 1 Sand Brown
Lacquer # 2 Grey
Lacquer # 3 Yellow-Green
Lacquer # 4
Lacquer # 5 Dark Green
Lacquer # 6 Black
Lacquer # 7 White

It is interesting, and telling, that no specific lacquer type, family nor formulation is mentioned. It would appear that a standard palette is what the government had in mind, however vague it might be given the number of available paints on hand which fit the various descriptions. Moreover, the specification of a sand brown colour is curious, in that no such colour is known to have appeared on any VVS aircraft during the period in question. And lacquer #4? It is mentioned, so this one is still a mystery.

*  For Russians there are two distinct blue colours, not just the one as in Western culture. Sinii is the darker shade of blue, and goluboi the lighter. Herein, I have translated goluboi as blue, and sinii as dark blue. Some fascinating material can be found in published literature as to where, exactly, the average Russian believes the border between the two colours lies.
