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.
