Michel Eugène Chevreul’s Des couleurs presents the French chemist’s color classification system distinguishing 14,400 hues and tones. The book’s plates, illustrating various tonal scales and color wheels, were produced in collaboration with René Henri Digeon by means of “chromochalcography,” an intaglio color printing technique using multiple steel plates. Des couleurs is a result of Chevreul’s research into dyes and color perception undertaken during his tenure as Director of the Department of Dyes at the Gobelins Manufacture in Paris.</div>
