An avant-garde movement accredited to Georges Seurat in 1886. It was incredibly popular in France, for the most part, but retained interest in other parts of northern Europe as well as Italy until the end of the 20th century. Similar to traditional Impressionist work, Neo-Impressionists were interested in landscapes and modern urban scenes. Neo-Impressionists also had an incredibly unique approach to color theory which relied on science-based interpretations of color and line which they incorporated into their use of Pointillist and Divisionist techniques (Chromoluminarism). Neo-Impressionists were greatly motivated by goal or achieving harmony from modern sciences and art. They were outspoken in anarchist theory, in addition to debates around the value of academic arts.
