Army camouflage colours were always recognized by a '7' or '8' in the first place until 1944. In the 1930s, the numbers were changed uniformly to four digits and the collection was renamed to 'RAL 840 R' (R for revised).Īround 1940, the RAL colours were changed to the four-digit system, as is customary. Prior to that date, manufacturers and customers had to exchange samples to describe a tint, whereas from then on they would rely on numbers. In 1927, the German group Reichs-Ausschuß für Lieferbedingungen (Imperial Committee for Delivery and Quality Assurance) invented a collection of forty colours under the name of 'RAL 840'.
