Predictions based on Munsell notation. I. Perceptual color differences

Predictions based on Munsell notation. I. Perceptual color differences For every pair of colors (j, k), the observers selected a pair of Munsell grays (Na, Nb) such that the lightness difference matched the color difference in size, and the scaled value of color difference was defined as djk = Va − Vb. On the basis of these data, where (j, k) are limited in the range that can be matched by djk < 4.0 V, the procedure was presented to define predicted values d̃jk for Munsell colors (J, K) between 4V and 7V directly from Euclidean d̂jk between points Pj and Pk in the current Munsell solid.

Abstract

For every pair of colors (j, k), the observers selected a pair of Munsell grays (Na, Nb) such that the lightness difference matched the color difference in size, and the scaled value of color difference was defined as djk = Va − Vb. On the basis of these data, where (j, k) are limited in the range that can be matched by djk < 4.0 V, the procedure was presented to define predicted values d̃jk for Munsell colors (J, K) between 4V and 7V directly from Euclidean d̂jk between points Pj and Pk in the current Munsell solid. The procedure is more practical than the multidimensional scaling representation. Inter‐point d̂jk are measured in the units of C in the (H, C) plane and the contributions d̂jk of 1C and 1V differences are assumed to be 1 and 2.3. Precision of predictions, RMS = {mean of djk − d̃nk)2}0.5, is 0.3 V (0.8 C) for 2‐D color differences (Vj = Vk). For the set of data on 3‐D color differences used in the present study, RMS = 0.6 V (1.7 C). These were compared with the precision of predictions by Judd, Adams–Nickerson formulae, CIE 1976(L*, u*, v*), and CIE94. © 1999 John Wiley & Sons, Inc. Col Res Appl, 24, 10–18, 1999
