Here are 212 RAL Classic plastic colors. I needed three colors out of the collection and decided I might as well create the whole palette. This comes with a simple plastic material, with a few adjustable parameters. (Roughness, IOR, Normal, Pearlescent)

RAL is an European color matching system which defines colors for paint, coatings and plastics. RAL Classic is the most famous and widely used system. 'RAL' is the abbreviation of 'Reichs-Ausschuß für Lieferbedingungen und Gütesicherung'. This name can be translated in English as 'National Commission for Delivery Terms and Quality Assurance'.
