Which painting technique developed during impressionism uses dots to create image?

The painting technique that developed during the Impressionist movement, which uses distinct dots of color to create an image, is known as Pointillism. This technique was first popularized by artists such as Georges Seurat and Paul Signac in the late 19th century. Pointillism involves applying small, individual dots of color to the canvas, allowing the viewer's eye to blend the colors at a distance, creating a vibrant and shimmering effect. This method emphasizes light and color, contributing to the artistic movement's objectives of capturing the essence of a moment or scene rather than its precise details. Pointillism represents a significant evolution in the use of color theory and optical mixing in art.
