Since 1927 RAL, with its authoritative standards, has formed the interface and communications foundation for providers as well as users of colours. At that time, on assignment from State and Economy, RAL developed a colour collection for paints and colours. The intention was to give the paint- and pigment industry assistance in the streamlining of their productions and to avoid any coordination problems in the use of colours, for the purpose of standardisation of delivery conditions. Originally the table consisted of 40 colours. Over the decades always in answer to demand the palette grew to the grand number of 2325 colour tones. Through strict quality control the users are being offered the highest precision. Thus in 80 years an exemplary success story was written, today the RAL-colours are a worldwide determining standard in industry, trades and design as well as for the professional colour users. RAL is the most famous color matching system used in the world. In colloquial speech RAL refers to the RAL Classic system, mainly used for varnish and powder coating but nowadays there are reference panels for plastics as well. The RAL company periodically adds new standards of color.
