RAL is a German color matching system, invented in 1927 by Imperial Commission for Delivery Terms and Quality Assurance (Reichsausschuß für Lieferbedingungen und Gütesicherung) on request of paints and varnishes manufacturers.
The Comission has set the standard for color space, dividing it into ranges and giving a unique numerical index to each color. Since then, RAL is constantly developing and adding new tints to meet the needs of the growing market. Numerous notations added to color samples ensure clear and concise communication method, understandable in many areas of the industry. This universal system of color selection is used almost in all areas where correct understanding of color is needed.
