The principles of harmony and contrast of colours [electronic resource] : and their applications to the arts
Chevreul's 1890 London treatise, translated by Charles Martel, sets out the principles of colour harmony and contrast for artists and designers, drawing on his work as a chemist and dye director. The plates are plain colour charts: pairs of discs with halos, striped swatches, and grids of coloured dots on cream paper, showing how neighbouring hues shift each other. A designer can take from them the simple logic of simultaneous contrast, where a colour looks different depending on its surround.
