The RLM system is probably the most widely known system of all paint systems in the 2nd world war, and a lot of modellers are known with it’s nomenclature. Still there is interesting information to be told about this system, and while other websites also do a very good job of accurately describing the colours with their matching modelling paints, they often lack the more rarely used colours, and wider context and history.

As with all pages of this type, the colours shown are an approximation. Monitors can change the colour displayed and don’t account for shading and glossiness.
In reality these colours would also fade over time, and different batches had slightly different tones.
The accuracy of the paints can be off. They’re mostly taken from the manufacturer, from painting manuals and bits on the internet. They should resemble the actual colour closely, but use at your own discretion.

Beginnings: The RAL

The RAL, Reichsausschuss für Lieferbedingungen, (State Committee for Delivery Conditions) was a German institute formed on April 23 1925, just after the first world war. While it was under supervision of the German Ministry of Economic Affairs, it was an legally independent entity. In the beginning it was tasked with quality assurance by labelling goods and services.

In 1927, the RAL published with it’s first colour standard for general industrial usage, RAL 840. By creating a system of standardized colours the cost of paints could be reduced due to economy of scale. By prioritizing local pigments, imports could be reduced as foreign currencies were scarce and the Reichs mark was worthless in foreign countries. The system contained 40 colours most widely used; 13 base shades and 27 more created by mixing those. During the following decade the amount of colours increased to more than 100 shades as new government organizations, such as the posts and railways, needed new shades. As a result the RAL 840 was split into multiple standards.

RAL 840 B

On the 1st of November 1927 the RAL 840B was published. This was and extendsion with a new range of 40 colours for vehicle usage.

RAL 840 B2

On April 30 1932 an updated version of RAL 840 B was published, which was designated RAL 840 B2 in June to avoid confusion. Over time, these colours proved insufficient and new colours were added via supplementary sheets, or Ergänzungsblätter.

RAL 840 R

In 1939-1940 this wild growth of colours led to a new numbering system under influence of the Wehrmacht, The RAL 840 R (=Revision). Under this reworked system every colour was given a four number code and a name. The first digit indicated the main group or shade. Each group started with the ‘pure’ shade, and moved in small intervals to the next ‘pure’ shade in the following group. This system was applied widely within all arms of the German government and armed forces such as the police, army, navy. It remains in use to this date as RAL 840 HR. At least initially it was also used by the air force, although copied via it’s own system.

RAL 1xxx	Yellow	RAL 6xxx	Green
RAL 2xxx	Orange	RAL 7xxx	Grey
RAL 3xxx	Red	RAL 8xxx	Brown
RAL 4xxx	Violet	RAL 9xxx	White and Black
RAL 5xxx	Blue

RLM

The RLM, abbreviation of Reichsluftfahrtministerium, was the German Ministry of Aviation. It was in charge of all matters concerning German aviation, such as aircraft development and standardization within the Luftwaffe, the German Air Force. The ministry was founded in 1933 and oversaw the standardization of, among other things, aircraft paints and camouflage patterns within the Luftwaffe.

When the RLM stopped using the RAL systems isn’t exactly known, but by March 1935, when the Luftwaffe was revealed, the RLM had already a system in place, largely similar to the RAL 840 R, however the system was already in use from at least February. Why the RLM choose to diverge from the RAL four digit to their own two digit codes is unknown, but it might be because the RAL was thought to be too unwieldy, or because a two digit code better fitted their Flugzeug Werkstoffen (Aircraft materials) number system, often shortened as Flw. number.

The Flw system

This was a new system by the RLM spanned the entire military procurement of materials and ranged from 0000 to 9999. These were sometimes subdivided with a decimal suffix to give additional information, such as material grade, treatment or colour. The first documentation of these occurred in 1935, in the ‘Fliegwerkstoffe.- Handbuch für die Auswahl der im deutschen Flugzeug-, Flugmotoren- und Luftfahrtgerätebau zu verwendenden Werkstoffe, Herausgegeben vom Reichsluftfahrtministerium Werkstoffabeteilung, 1935’ (Aeronautical materials.- Handbook for the selection of materials to be used in German aircraft, aircraft engines and aircraft equipment construction, Part I: Metallic materials, issued by the RLM material department, 1935).

Range	subdivision
0000-3999	.0-.9, material treatment	metals: steel, gun metal, brass, bronze, aluminium magnesium alloy, etc.
5000-6000		Various rubbers, leather, textiles, paper, etc.
7100-7199	none initially, later .- or .00-.99	Aircraft lacquer bases. At the end of the war only ~50 codes had been utilized.
7200-7299	N.A	Paint thinners
7300-7499		Colours of corrosion proofing of materials
7500-9999		Lime, asbestos, ceramic materials and glass.

The 7100-7199 range here only described the base lacquers. And while these often had a natural colour, this could vary from batch to batch. To identify the specific colour, a two digit code would be used as suffix. For example, 7102.02 would be the 7102 lacquer, which is almost translucent with a slight green tint mixed with the RLM 02 colouring pigments. .00, .- and .99 held special meanings: 00 meant a clear finish, showing the colour underneath. If no pigments were added to the lacquer the .- suffix was used. This was later replaced with .99 as early computers (Hollerith machines, or Tabulating machines) couldn’t handle the dash.

These two digit codes would become known as the well known RLM colours. It should be noted however that these first RLM colours were relabelled RAL 840 R colours.

100 numbers were allocated in blocks of 20 (21 for the last block) for the paints.

Range	German name	Notes
00-19	Grundraben (Innen-Aussen-anstricht	Base colour (Internal-external base finish)
20-39	Kennzeichnungsfarben	Marking colours
40-59	Sonderfarben	Special colours
60-79	Tarnanstrichfarben	Camouflage colours
80-100	–	This block had no purpose allocated, but might have been intended as an overflow block, as it was used as such with new camouflage colours being placed in this range.

3 February 1935: Warnecke und Böhm company letter

The first documented appearance of the new RLM system is in a company letter from the paint manufacturer Warnecke un Böhm from 3 February 1935. It includes a written list of colours, including multiple that don’t appear on later RLM publications, such as 07 saturnrot, 32 hellgelb en and silbergrau.

This would indicate that the system was already in place for at least some time, however any documentation about the incarnation of the system have been lost to date.

1936: Richtlinien für die Entwicklungen geeigneter Flugzeuglacke

In 1936 a document addressed to the German paint manufacturing industry was published titled “Richtlinien für die Entwicklungen geeigneter Flugzeuglacke” (Guidelines for the development of suitable aircraft paint). It was addressed to the German paint manufacturing industry, likely by the RLM (This isn’t actually known, but no other government branch would have vested interst in publishing such a document).

The original document hasn’t been found, only a reissue “2/1938”. The B. likely means a 1st part existed of this document. The main statement of the document was that all paints should use locally procured materials, as imports were difficult due to scarecity of foreign currency. It also stated that, if the RLM requested as such, manufacturers had to grant other companies licences and knowledge to start-up paint production.

1936: Luftwaffen Dienstvorschriften L.Dv. 521

The RLM regulations for colour shade, production and application were proclaimed by Luftwaffen Dienstvorschriften L.Dv. 521 (=air force regulations L.Dv. 521) starting early 1936. It was split in three parts:

• L.Dv. 521/1 Behandlungs- und Anwendungsvorschrift für Flugzeuglacke, Teil 1: Motorfleugzeuge.
  Handling and application instructions for aircraft paints, Part 1: powered aircraft
• L.Dv. 521/2 Behandlungs- und Anwendungsvorschrift für Flugzeuglacke, Teil 2: Segelflugzeuge.
  Handling and application instructions for aircraft paints, Part 2: gliders
• L.Dv. 521/3 Einer Vorschrift zum ausbessern von Fleugzeuglackierungen
  specification for touching up aircraft paintwork

The earliest known surviving version, a revision of L.Dv. 521/1, was issued in march 1938. Some colours, including the RLM 61, 62 and 63, were still correlated to the RAL 840 R system. (RAL 8019, 6002 and 7004 respectively.)

In November 1941 the L.Dv. 521/1 was revisited, although it was still marked as Ausgabe 1938 (= edition 1938). The L.Dv. 521/1 (1941) contained three new colours: RLM 74,75 and 76. RLM 61, 62 and 63 were no longer used for aircraft and done away with. Strangely RLM 02 and RLM 66 were changed. RLM 66 was changed from RAL 7019 to RAL 7021. RLM 02 was made more intense and darker.
RLM 78 and 79 were not ready at the time of printing and were attached last-minute by loose paint chips stuck to a blank page in the manual.

Full Colour Table

RLM 00-19, Grundfarben

The purpose of this block is to denote primer colours, however during the war most colours were used as regular camouflage as well. Of this block only five numbers appear on RLM colour charts, RLM 00, 01, 02, 04 and 11. Two more appear somewhere on official documents; RLM 03 and 07. Their exact purpose remains unknown however. RLM 05 doen’t appear on official charts either, but was widelely used for non-military purposes. RLM 06, 08, 09 and 10 seem to have been assigned at some point, but no documentation has been found.

RLM 40-59, Sonderfarben

Translating to “special colours”, this block is the least filled. There isn’t much known about these colours, and as far as we know they were scrapped before the publication of the L.Dv. 521 in 1938.

RLM 60-79, Tarnanstrichfarben

Camouflage colours, these colours were used as external finishes on aircraft.

RLM 64 is curiously missing from the list. It hasn’t been found in any official documentation, but it is sometimes depicted by secondary sources as a olive green or light blue. Some theories about it being an export colour on Turkish He-111’s exists as well. However these are all unsourced speculation, an thus I opted to not include RLM 64 in the table.

RLM 80-100, unnamed block

This block doesn’t have an official name and was likely meant as an overflow block. As in practice, this was used as such after the camouflage colour block was filled. The other blocks didn’t have enough colours assigned to completely fill them.

Some secondary sources extend this list with RLM 84 and beyond, but no official documentation of these paints existing have been found.

	Experimental colour for usage in the Mediterranean theatre. It was to be used with RLM 72 for seaplanes and RLM 70 for land based aircraft. Widespread usage is debated, but there are accounts of Junkers Ju 88 bombers being painted in a dark blue camouflage. The colour first appears in a monthly rapport, E-stelle Travermünde, in November 1943. It’s official recipe, Flieglack 7121.83, also gives a dark blue colour when recreated. It was experimented with, but no information about widespread usage exist and documentation regarding official implementation is still missing, however eye witnesses indicate that blue painted aircraft did fly around at from 1943 onward. For more information, see The Curious Case of RML 83

RLM 99, or Flw. xxxx.-

In official documentation the colour 99 sometimes appears. Being out of sequence, this colour was used to designate that the precise shade is unimportant. In practice, this often meant that no colouring pigments were added to the base lacquer, or a small amount of to aid with applying an even coat. Initially a dash was used (eg. 7101.-). This dash however wasn’t compatible with tabulating machines, early computers used for summarizing information on punch cards. Therefore it was replaced with RLM 99 (e.g. 7101.99). When a small amount of pigments were added, this could be noted after the Flw. number, eg 7140.99 gelb lasierend (transparent yellow).

pre 1936 Early Monotone camouflages

Initially German aircraft wore overall silver and grey finishes. These were standardized in 1936 with the L.Dv. 521. RLM 02 and RLM 63 differed visually little from each other. Trainers also used the silver livery as the colour provided better visibility in the air.

1944-1945 Late war splinter Scheme

In August of 1943, a notice was sent out announcing the future introduction of RLM 81 and 82, which were to replace RLM 70 and 71. This was made official by a Sammelmitteling in July 1944, around the time losses on the ground started to exeed losses in the air. Existing stock of RLM 70 and 71 were to be used up and replaced by RLM 81 and 82. If necessary, RLM 70 was to be mixed with 82, and RLM 71 with 81 (further increasing the amount of late war green shades). A month later, RLM 65 was to be replaced by RLM 76.
A likely reason for this change was that RLM 70 and 71 contained chromium and RLM 65 contained Cobalt, bot necessary for the production of high-grade metals.

1941-1944 Tropical Camouflage

Luftwaffe units started to be deployed in North Africa somewhere between late January and March 1941. At the time, no suitable camouflage colours for the sandy, Saharan desert were available. The first mention of the tropical scheme comes from an inspection document to a depot in Erling, Germany, which describes the three lacquers.
Curiously, only colour chips for RLM 78 and 79 were added to the L.DV. 521/1 of 1941. Somewhere after November 1941, RLM 78 was changed to a slightly lighter shade, while RLM 79 was changed to a darker, browner shade.

RLM 80 wasn’t always used, especially on later fighters such as Bf 109’s and Fw 190’s

Ever after the retreat from Africa, the colour scheme was still used to some extend in Italy until 1944 and the eastern front after units were send there.

Unsure and wrong colours

These designations I’m not sure about, if they even exist. Especially the colours 64 and 67 are suspiously missing from the range, implying that they might exist, or at least have been considered to the point of getting an RLM number reserved. However as of yet no official documents about their existence have surfaced.

RLM number	Colour	equivalents	Gunze	Tamiya	Vallejo	Hataka	MRP	AK	Ammo MIG
9	Gelbgrün
RLM 64
	sometimes depicted as a light blue colour, sometimes as an olive green, supposedly it was on colour charts before the 1936 revision of the L.Dv. 521, however no original evidence of it’s existence or usage has surfaced as of yet. export colour ?
RLM 67	Weiß
RLM 84
	RLM designation is erroneous and this colour was most likely the late variant of RLM 76.
