If you wish to translate a colour from one system to another, you can use the NCS colour translation service. They translate to and from most colour systems/ charts including:
NCS, Pantone Coated/Uncoated/Textile/Colour bridge etc. RAL and CMYK coated/uncoated
You can find more information about this service here.
Architects and Designers will find it useful to own physical guides from RAL, Pantone and NCS if they are regularly using colours from the different colour systems. This will enable a cross check to be done on site or with the client.
The NCS Colourpin devices can also be used to measure a colour target and find the closest NCS colour.
Please note that if you need to translate your colour from NCS to CMYK, RGB or Lab notation, you can also use the NCS+ Web or use the NCS Colourpin device.
