On Saturation and Related Parameters Following Guth's ATD Colour-Vision Model

摘要

In this work, we have examined the influence of different parameters both on perceived saturation and sat- uration discrimination with unrelated clours, on the basis of S.L.Guth's CA90 colour-vision model and its subsequent modifications. Our analysis of perceived saturation covered (1) spectral saturation functions at constant luminance,(2) saturation functions in constant colorimetric purity loci,(3) saturation vs, colorimetric purity functions, (4)saturation vs. luminance functions in the 1-1000 td range, and, finally, (5)the equal saturation loci in the xy color diagram.
