Abstract

It has been noticed that the lightness dependency of equal chroma loci of the nonlinear color‐appearance model already reported deviates markedly from that of equal Chroma loci of the Munsell scheme. to solve this problem, the new chroma CN of the model is proposed by applying the correction of lightness LA to the chroma C previously used. the chroma C is now used to predict the saturation of the newly revised model. the introduction of CN improves significantly the agreement of lightness dependency between the model chroma, the Munsell Chroma, and the NCS chromaticness at various lightness levels. the formulation for the revised nonlinear colorappearance model is given in the Appendix.
