Focus on this artwork and analyze the Theoretical foundations and development.
Divisionism is the technique of painting separate dots or patches of different colors in close proximity that interact optically in the viewer's perception to generate more luminous colors. The paints are not actually mixed but viewed close together, so the separate colors of light reflected by the paints mixes in the eye and brain; the process is called additive mixing and is also used by computer monitors. This is different from mixing different paints together to produce a new color by subtractive mixing, which is also how laser printers produce colors. Despite the theory, Seurat's paintings don't actually use true additive mixture, since the colors reflected by his paints as he used them don't actually mix in the eye. Instead, Seurat used highly contrasting colors in close proximity, but not close enough to mix additively; this effect is called simultaneous contrast, which creates a mild shimmering appearance and slightly increases the colors' apparent visual intensity.Impressionism originated in France in the 1870s, and is characterized by the use of quick, short, broken brushstrokes to accurately capture the momentary effects of light and atmosphere in an outdoor scene. The Impressionists sought to create an "impression" of a momentary scene as perceived by the viewer, rather than a mechanically precise replication of the scene. Divisionism, also known as Pointillism, developed from Impressionism in the 1880s. The Divisionists used a technique of placing small, distinct dots of color next to one another on the canvas, rather than mixing the colors on the palette. This created a more vibrant and dynamic effect, but also required a higher level of skill and precision. Neo-Impressionism emerged in the late 19th century, used more precise and geometric shapes to build compositions and was strongly influenced by the scientific study of color theory and optical color effects, to create a more harmonious and luminous painting.Scientists or artists whose theories of light or color had some impact on the development of Divisionism include Charles Henry, Charles Blanc, David Pierre Giottino Humbert de Superville, David Sutter, Michel Eugène Chevreul, Ogden Rood and Hermann von Helmholtz.
