In The Principles of Harmony and Contrast of Colours Michel-Eugène Chevreul (d. 1889) made major scientific contributions to the fields of chemistry and colour. Among other works, he invented a three-dimensional colour classification system, which he used to manufacture a colour atlas showing colour circles and monochrome lightness scales.
