Pointillism is a technique of painting which creates an effect of varying tone through the use of small dots or strokes side-by-side. It was developed by the French artist Georges Seurat in the 1880s. Pointillism is characterized by a high level of detail, rich colors and an almost shimmering effect. Pointillists often appear to reject the idea that "art should accurately reproduce reality," instead focusing their attention on brighter color combinations and more simplified forms which portray their subject matter in a bolder manner. Points are not necessarily all of equal size or shape, and are used to produce an effect of spontaneity. This art style can be recognized by the presence of small dots or brush strokes, which are generally applied in different directions.
