Fixed range scales applied to the evaluation of color: Comparative analysis between the Munsell system and the natural color system
In this article, we discuss the effect of anchoring on the estimation of chromatic variables, which occurs when fixed range scales are used in psychophysical measuring. In order to do this, we compare the Munsell System and the Natural Color System (NCS), and an alternative system that employs a sca...
