RAL colors are standardized colors issued by RAL gemeinnützige GmbH (a subsidiary of RAL Deutsches Institut für Gütesicherung und Kennzeichnung) in the form of color systems and color catalogs. Each color is assigned a unique number, allowing colors to be precisely communicated without the need for color samples.
The "RAL Classic" system consists of 216 colors. Each color has a unique four-digit code. RAL Classic colors are widely used in architecture, design and industry and have become a standard reference for color communication. RAL Classic colors range from bright, bold tones to subtle pastels and are used in a variety of applications, such as vehicle painting, interior design and product branding.The "RAL Design" system was introduced in 1993. It includes 1824 standardized colors based on the internationally used Lab colorimetric system defined by the Commission Internationale de l'Éclairage (CIE) in 1976. The colors are systematically arranged according to hue (H), lightness (L) and chroma (C).
For the representation on screens reference tables are used which - like here - assign the RAL code to a HEX code as best as possible.
