The RAL design system has been developed for professional color design, particularly useful for the construction industry. It contains 1688 colors arranged in a regular order. So the seven digit colors are divided into individual RAL colors. Unlike the classical RAL color chart, the color codes in the RAL design system are not arranged arbitrarily. These seven digit colors display technical measurements of chromaticity, brightness, and color saturation (HLC). Due to the color numbering system being based on the international standard CIE color solid, the coding is clear and easy to understand. You can find any color you want to choose, making it an outstanding tool for designers and other color related personnel. Using this system to coordinate color combinations will become very easy.
