Do you require binding colour samples of all 216 RAL CLASSIC colours for accurate colour matching and quality control? Containing 216 RAL CLASSIC colours as A6 swatches, the RAL 840-HR colour primary standard set aids accurate colour selection and design, enables reliable colour matching and ensures strict quality controls. Each colour sample is shown on a separate A5 card that also notes the colour’s XYZ value, its colour distance to the original RAL standard and the reflectance curve.
