点彩法, or "Pointillism," is a painting technique that uses small dots of color applied in patterns to form an image. This method allows the viewer's eye to blend the colors from a distance, creating a vibrant and luminous effect. It was developed in the late 19th century as part of the Post-Impressionism movement. The technique is closely associated with artists like Georges Seurat and Paul Signac, who aimed to explore the science of color and light. By carefully placing dots of pure color, they sought to achieve a greater intensity and harmony in their artwork, moving away from traditional brushwork.
