   pointillism  is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. georges seurat and paul signac developed the technique in 1886, branching from impressionism. the term "pointillism" was first coined by art critics in the late 1880s to ridicule the works of these artists, and is now used without its earlier mocking connotation. the technique is also known as divisionism. the movement seurat began with this technique is known as neo-impressionism.ruhrberg, karl.
