A. H. Munsell was an American artist and color theorist best known for developing the Munsell color system, which provides a systematic approach to color classification based on three dimensions: hue, value, and chroma. His influential work, "A Color Notation," outlines this innovative color notation system, which has been widely adopted in various fields, including art, design, and education.
