Spacing in the Munsell Color System Relative to the Coloroid Color Systems

Spacing defined by various Munsell hue and chroma steps are analyzed, applying diagrams resulting from transformations between the Colorid and the Munsell color systems, displaying colors of both color systems with the same Y tristimulus values. After comments on spacings derived from identities, similarities and differences between both color systems, unevennesses uninter‐pretable from differences of color system constructions are attributed either to uniform variation of color stimult followed by uneven variation of color perceptions, or to uncertainties of human color perception at several spots of the color space sufficient to be noticeable in spacings in perceptually uniform color system, such as the Munsell color order system © 1994 John Wiley & Sons, inc.
