RAL color System

Description

In 1927 the German Reichsausschuß für Lieferbedingungen und Gütesicherung" (State Commission for Delivery Terms and Quality Assurance) invented a collection of 40 colors under the name of "RAL 840". Prior to that date manufacturers and customers had to exchange samples to describe a tint, whereas from then on they would rely on numbers.

After it was revised in 1930s with four digits, again revised in 1961 which consist of 210 & is in use to this day.

The RAL Design System has been developed for professional color design. It contains 1688 colors arranged in a systematic order. All the 7-digit color shades are defined as individual RAL Colors. The difference between this and the RAL classic color collection is that the color codes of the RAL Design System are not arranged arbitrarily. They indicate the technologically measured values of Hue, Lightness and Chroma.
