Albert Henry Munsell was a pioneer of colour theory. His Colour Notation established theories for categorising colour around three dimensions: hue, value (lightness), and chroma (purity). These elements were proposed to produce any particular colour or differentiate between those of the same character. First published in 1905, Munsell's innovative theory offered insights into colour harmony, relationships, and the psychological impact of colours. It spurred significant advancements in colour science, art, and design, standing as a cornerstone text alongside those published by Michel Chevreul and Ogden Rood.

This new edition from Art Meets Science combines Munsell's seminal A Colour Notation with all fifteen full-colour plates from Atlas of the Munsell Color System, an introduction by Munsell, and an essay on colour by Bonnie E. Snow. An essential colour manual for those studying colour theory or with an interest in colour application, colour behaviours, and the history of colour theory.
