Answer
Pointillism, the answer to Pissarro's technique, involved the use of tiny dots of pure color applied in patterns to form an image. Unlike traditional blending, this method allowed colors to optically mix in the viewer's eye, creating a vibrant and luminous effect. Pointillism became a defining characteristic of Neo-Impressionism, a late 19th-century art movement that sought to scientifically analyze and depict the effects of light and color.
