Signac adapted for the lithographic process the style he and George Seurat (1859-1891) developed in the 1880s for painting: pointillism. Brilliantly colored dots were juxtaposed to produce a full optical tonal range more luminous than can be obtained from pigments mixed on the palette. Saint-Tropez, printed in six colors (blue, blue-gray, red, pink, yellow, and green), demonstrates that lithography was a perfect vehicle for translating these artists' scientific ideas about color.
