Pointillism is a technique of painting where small dots of pure color are applied in patterns to form an image. When viewed from a distance, the colors blend together in the eye of the observer. It was developed by Georges Seurat in the 1880s as part of the Post-Impressionist movement. Other masters of Pointillism include Paul Signac, Charles Angrand, and Henri-Edmond Cross. Seurat's most famous Pointillist work is A Sunday Afternoon on the Island of La Grande Jatte.
