Pointillism is an art form in which images are constructed using individual dots rather than brush strokes. The movement developed in the 19th century as a successor to impressionism. Rather than mixing colours on a palette, pointillism relies on the optical effect produced by numerous tiny dots of unmixed colour placed next to each other in order to create light effects. An early work that exemplifies this technique is ‘A Sunday Afternoon on the Island of La Grande Jatte’ by French artist Georges Seurat, who is considered the founder of this style.
