• Because mixing pigments together can sometimes result in a muddy or flat effect, optical colour mixing is used to give a visually brighter, more intense, and clearer result.
  • The example to the right is a detail of Georges-Pierre Seurat - "A Sunday on La Grande Jatte" - 1884
  • Optical colour mixing is often used in creating mosaics. Tiny pieces of pure (not mixed or marbled) coloured tiles are interspersed to produce the effect of many other intermediate colours.
  • The same process is also used in creating weaves and tapestries by intermingling coloured yarns or threads, letting the viewer’s eye create the impression of many hues and values.
  • And everyday when we look at our computer and/or television monitors we are constantly seeing the result of retinal fusion.
