Pointillism (the practitioners called it Divisionism or Chromo-luminarism) was Georges Seurat's systematic answer to Impressionism: instead of spontaneous broken brushwork, small dots and dashes of pure, unmixed color are placed side by side, and the mixing happens optically in the viewer's eye. Seurat grounded the method in contemporary optical science, and Paul Signac turned it into doctrine. The result is a shimmering, luminous surface and an oddly calm, frozen world - figures become statuesque silhouettes. The technique also demanded method: a Seurat canvas could take years of tiny applications. Though the movement was short-lived (Seurat died at 31), its color science fed directly into Fauvism and every later experiment with optical color, up to screen pixels.
