The laws of contrast and colour and their application to the arts of painting, decoration of buildings, mosaic work ...
Chevreul's 1861 London treatise on colour, translated by John Spanton, sets out the laws of simultaneous contrast for painters, decorators, mosaicists and other makers of coloured work. Its plates are flat colour charts: squares and rings, star grids, striped bands and a blue disc haloed in orange, arranged to show how neighbouring hues shift each other. A designer can take from them ready-made colour pairings and the way a ground changes the look of a motif placed on it.
