Abstract

To use MacAdam charts for chromaticity difference with measurements on a tristimulus colorimeter, one must convert the reflectance readings of sample and standard to CIE chromaticity coordinate differences by a series of calculations involving several steps. Alignment charts are described by which the chromaticity differences can be read directly from the reflectance ratios. The application of this method to the colorimetry of near-white samples is described, and a chromaticity-difference chart is presented from which one can read both the nature of the difference in Munsell terminology and the magnitude in MacAdam units.
