Pointillism and Chromoluminarism

Chromoluminarism, or Divisionism, was a style of painting in which colors were separated into individual patches or dots that created an optical interaction with the viewers eye. The colors used were very pure and appeared mixed to the viewers eye. Pointillism uses similar patches and dots, but the key differences between the two styles is that Divisionism uses longer brush strokes, making small comma like dots, like Seurat's Grandcamp, Evening, whereas Pointillism uses much smaller brush strokes which result in very tiny dots and points. The other key difference is usually in the subject matter. Pointillism focuses around urban life and secular themes like the Bathers at Asnieres or A Sunday on la Grande Jatte. While Divisionism focuses on social themes and used Christian symbolism.
