The Principles of Harmony and Contrast of Colours and Their Applications to the Arts

Michel-Eugène Chevreul's work, The Principles of Harmony and Contrast of Colours and Their Applications to the Arts, is a foundational text in understanding color theory. Chevreul, a French chemist, explored how colors interact when placed next to each other.12

His key contribution is the "law of simultaneous contrast," which states that adjacent colors mutually influence each other, with each color imposing its complementary color onto the other. This means that colors can appear more intense or altered depending on the colors surrounding them. Chevreul's research provided a systematic way to represent colors and understand their effects, influencing artists, designers, and decorators. His work significantly impacted movements like Impressionism and Post-Impressionism, as artists experimented with optical mixing of colors.1324
