Exposé d'un moyen de définir et de nommer les couleurs, d'après une méthode précise et expérimentale, t. 2, Atlas
Chevreul's 1861 atlas volume accompanying his method for defining and naming colours, published in Paris by Didot as part of the Mémoires of the Académie des Sciences, and aimed at scientists, dyers and artists. The pictures are hand-coloured chromatic circles, each a wheel of radiating colour bands with a centre label, and a designer might take from them a systematic way of ordering hues by tone and saturation into a clear grid.
