Pointillism was an art style developed by Georges Seurat in the 1880s where paintings are created using only dots of color. When viewed from a distance, the eye blends the dots through optical blending. Seurat's most famous work, Sunday Afternoon on the Island of La Grande Jatte, took two years to complete and contains over 3 million dots applied one at a time with patience. Pointillism caught on as an art movement where color dots create the illusion of blended color from afar.
