A theory or practice which is a further development, on more rigorously scientific lines, of the theory and practice of Impressionism, originated by George Seurat (1859-91), and carried on by Paul Signac (1863- -) and others. Its method is marked by the laying of pure primary colors in minute dots upon a white ground, any given line being produced by a variation in the proportionate quantity of the primary colors employed. This method is also known as Pointillism (stippling).

This art movement of the late 19th century was based mainly on the work of George Seurat. Also known as "Pointillism," the technique uses small dots of undiluted pigment and the juxtaposition of strong, contrasting colors to create a vibrant effect.
