A Color Notation / A measured color system, based on the three qualities Hue, Value and Chroma

This work presents a systematic, three-dimensional approach to color that defines hue, value, and chroma and shows how they combine to specify any color. It outlines practical instruments and charts including a color solid and a color sphere, explains a notation for recording colors, and offers measured exercises, illustrative models, and classroom courses for teaching color perception. Chapters address color names and common misnomers, color mixture and prismatic colors, pigment balance, and color harmony, with appendices containing children's measured studies and technical notes. Emphasis is placed on precise terminology, reproducible measurement, and a graded curriculum to develop reliable color discrimination.
