Abstract

The NCS (Natural color system) is a color order system, which has been further developed by Hard and his collaborators. NCS Notation is being discussed in the international standardization. This color notation is based entirely on the perception of color as a visual and qualitataive phenomena. The ISO/TCl87 domestic committee in Japan is continuing experiment on teh validity of this NCS notation. I studied the NCS Three Attributes Diagram and used the NCS attributes (whiteness, blackness, and chromaticity). These three NCS attritubutes can be seen in the bargraph scale, which measures the percentage of each attribute. The subjects in the experiment were requested to report their visual perception: how each color appeared in their perspective. The results of the experiments were based on the reported and calculated tests using the diagram of NCS notation.
