RAL is a colour matching system used across Europe and is mainly used for varnish and powder coating. Since 1927 RAL has produced a succinct language when it comes to the use of colour. RAL is a standardised method for categorising colours into colour numbers and names; to enable you to choose your colour selection from RAL DESIGN or RAL CLASSIC; however, for CAD & MAC solutions, choose from RAL DIGITAL.
Please note that RAL do not make any type of coating or paint. RAL is only a colour notation system that only acts to standardise colour; our colour cards and fan decks provide the end user with precise colour standards and their corresponding colour codes.
