NOTE:The Munsell colour notation was originally defined using Illuminant C at 2°. In order to be able to compare colours on this site, this has been changed to CIE 1964 D65 10° using the xyY values and the transformation defined in ASTM D1535-14 (reapproved 2018), in which there may be errors.

These close alternatives are therefore given for guidance only. Always visually check before any major purchase.

The information and the colours depicted are also for guidance only. The displayed colour will depend on your monitor and browser and pearl or metallic colours have not been included. The finished colour, therefore, may not be as shown here.

We always recommend a visual check before any major purchase.
