Broken colour is a technique which was introduced by the NeoImpressionists), whereby colours on the canvas are made up of small flecks and dashes of paint. The development of colour theory by the late 19th century played a pivotal role in shaping the Neo-Impressionists’ style. They acknowledged the different behaviors exhibited by coloured light and coloured pigment. While the mixture of the former created a white or gray colour, that of the latter produced a dark, murky colour. As painters, NeoImpressionists had to deal with coloured pigments, so to avoid the dullness, they devised a system of pure-colour juxtaposition. Mixing of colours was not necessary. The effective use of pointillism produced a luminous effect, and from a distance, the dots came together as a whole displaying maximum brilliance and conformity to actual light conditions.
