The Munsell color system is a color space developed in the early 20th century to describe colors as three components: hue, value, and chroma. Munsell color charts are used to quantify and standardize colors, facilitating communication and color matching in various industries. To inquire about the Munsell color chart, one would typically refer to a standardized chart with color samples and their corresponding numerical values for hue, value, and chroma.
