The Hue and Tone System, which is intuitive and systematic, was developed for psychological study and marketing color research. It is based on the Munsell System with reference to the ISCC-NBS naming method. As a base, chromatic colors are organized in 10 hues and 12 tones, and there are 10 achromatic colors.

The tone of a color is the result of the interaction of two factors: value or brightness, and chroma or color saturation. The tones range from vivid and bright to subdued and dark.
This two‐dimensional color system makes it easier to classify color data, to grasp the pattern of researched colors or to make time series analysis.
