Performance of CIE94 for nonreference conditions

Dental ceramics: A CIEDE2000 acceptability thresholds for lightness, chroma and hue differences

“…30,31 In general, it has been assumed that texture affects only lightness tolerance but does not affect chroma or hue tolerance. 11,12,32 Our experimental results showed higher values for CIEDE2000 acceptability thresholds for lightness compared to chroma or hue thresholds, which, as mentioned above, might be due to surface texture of the sample.…”

Influence of random-dot textures on perception of suprathreshold color differences

“…For textile samples the CIE has specifically recommended 1,3 the use of k L =2, k C = 1, and k H = 1. These values, accepted and used by several authors, [6][7][8][9] assume that texture in textiles affects only lightness tolerances but not chroma or hue tolerances. The accuracy of this recommendation is not yet well understood, and additional research has been called for.…”

“…The accuracy of this recommendation is not yet well understood, and additional research has been called for. 10,11 In addition, although some recent publications 6,[12][13][14][15] have clearly shown the strong effect of texture in perceived color differences, there are differences in the parametric factors computed, perhaps induced by the dissimilarities in the textures studied. Furthermore, typically only lightness tolerances for textured samples have been studied, 12,15 although investigation of chroma and hue tolerances has been claimed.…”

A preliminary comparison of CIE color differences to textile color acceptability using average observers

“…4 In addition, CIE94 has been validated only for unrealistic and artificial standard reference conditions and color pairs with CIELAB ⌬E units less than 5.0. 10 Literature previous to the development of CIEDE2000 is undecided as to whether CMC or CIE94 performed better, 2,3 while other literature report that CIE94 performs best. 5,11,12 However, CMC is the recommended equation of the AATCC and is widely used throughout the textile industry.…”
