What quality distinguishes one color from another according to Munsell?

The quality that distinguishes one color from another according to Munsell is hue. Hue refers to the distinctive characteristic of a color that allows it to be identified as red, blue, green, etc. In the Munsell color system, hue is one of the three principal attributes of color, alongside value (lightness) and chroma (intensity or saturation). Hue provides the basic identity of a color, differentiating it from others within the color spectrum.

Understanding hue is critical in interior design, as it impacts the visual appeal and emotional response of a space. Selecting the right hue can significantly influence the overall atmosphere of a room.

Other options, while related to color, describe different qualities. Value pertains to how light or dark a color is, which affects the depth and contrast in design. Tonal quality is a broader term that is not specifically defined within the context of Munsell's system. Brightness can relate to the perception of lightness of a color but does not specifically categorize the color itself like hue does.
