a theory and technique developed by the neo-impressionists, based on the principle that juxtaposed dots of pure color, as blue and yellow, are optically mixed into the resulting hue, as green, by the viewer.
Also called: divisionism the technique of painting elaborated from impressionism, in which dots of unmixed colour are juxtaposed on a white ground so that from a distance they fuse in the viewer's eye into appropriate intermediate tones
[C19: from French, from pointiller to mark with tiny dots, from pointille little point, from Italian puntiglio, from puntopoint]
