Abstract

Lightness and saturation, though independent in a physical sense, have often been seen to be psychologically related. The first experiment uses a multidimensional scaling technique to again verify this nonindependence for untrained Os. A further experiment, using a matching technique, quantifies this relationship, giving the extent of the error in lightness for varying levels of saturation. This relationship is found to be independent of hue if saturation is measured by the colorimetric purity of the hue. Errors in value (lightness on the Munsell system) were found to be linearly related to colorimetric purity.
