Pointillism
Optical color: thousands of small dots that mix in the eye.
Pointillism (also called divisionism or neo-impressionism) is a painting technique in which small, distinct dots of pure color are applied in patterns that the viewer's eye blends into a single tone at a distance. The technique was systematically developed by Georges Seurat in the 1880s.
Scientific basis
Seurat's method was rooted in nineteenth-century optical theory, especially the writings of the chemist Michel-Eugène Chevreul on simultaneous contrast and the physicist Ogden Rood on additive color mixing. Both argued that two colors placed side by side appear more luminous than the same two colors physically blended on the palette. Pointillism is the technique that puts that theory into systematic practice.
Seurat and the Sunday afternoon
The defining work is Seurat's A Sunday Afternoon on the Island of La Grande Jatte (1884–86), painted with millions of tiny dots over more than two years. Seen from a few metres away, the dots resolve into figures, parasols, sailboats, dogs and trees; seen close up, the painting is an almost abstract field of multicolored marks.
Signac and after
After Seurat's early death in 1891, Paul Signac became the movement's leading theorist and practitioner. His D'Eugène Delacroix au Néo-Impressionnisme (1899) codified the method, and his palette grew progressively bolder: by his mature work the dots had enlarged into mosaic-like rectangular touches of saturated color. The method influenced Henri Matisse, André Derain, the Italian Divisionisti Giacomo Balla and Umberto Boccioni, and reaches into early abstraction.
How to recognise it
From a distance, a Pointillist painting looks like a typical Impressionist scene — landscape, harbour, café — but with an unusually luminous, slightly vibrating surface. Step closer and the surface dissolves into discrete dots or small marks of unmixed pigment. The palette tends toward complementary contrasts (orange/blue, red/green, yellow/violet) chosen for maximum optical intensity.
