Pointillism (ˈpwæ̃tᵻlɪzəm, USˈpwɑːn-,_ˈpɔɪn-) 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 coined by art critics in the late 1880s to ridicule the works of these artists, but is now used without its earlier pejorative connotation. The movement Seurat began with this technique is known as Neo-impressionism. The Divisionists used a similar technique of patterns to form images, though with larger cube-like brushstrokes.
The technique relies on the ability of the eye and mind of the viewer to blend the color spots into a fuller range of tones. It is related to Divisionism, a more technical variant of the method. Divisionism is concerned with color theory, whereas pointillism is more focused on the specific style of brushwork used to apply the paint. It is a technique with few serious practitioners today and is notably seen in the works of Seurat, Signac, and Cross.
From 1905 to 1907, Robert Delaunay and Jean Metzinger painted in a Divisionist style with large squares or 'cubes' of color: the size and direction of each gave a sense of rhythm to the painting, yet color varied independently of size and placement. This form of Divisionism was a significant step beyond the preoccupations of Signac and Cross. In 1906, the art critic Louis Chassevent recognized the difference and, as art historian Daniel Robbins pointed out, used the word "cube" which would later be taken up by Louis Vauxcelles to baptize Cubism. Chassevent writes:
M. Metzinger is a mosaicist like M. Signac but he brings more precision to the cutting of his cubes of color which appear to have been made mechanically [...].
The practice of Pointillism is in sharp contrast to the traditional methods of blending pigments on a palette. Pointillism is analogous to the four-color CMYK printing process used by some color printers and large presses that place dots of cyan, magenta, yellow, and key (black).
