Code des couleurs : à l'usage des naturalistes, artistes, commerçants et industriels : 720 échantillons de couleurs classés d'après la méthode Chevreul simplifiée
A French colour-reference manual by bookseller-publisher Paul Klincksieck and Th. Valette, issued in Paris in 1908 with 720 numbered samples arranged by a simplified Chevreul system for naturalists, artists, merchants and manufacturers. Pages hold flat printed swatches in grids and strips, each keyed by number under headings like "Rouge," giving designers dated pigment palettes, tinted-paper grounds and numeric labelling layouts.
