This is a chronology of various attempts over the past four centuries to visually organize and understand color. It showcases a range of forms and methods, from simple color wheels to multi-layered pyramids, and from scientific systems to those based on human emotion. Many of the images are sourced from Sarah Lowengard's The Creation of Color in Eighteenth-Century Europe (2006), which is highly recommended for those interested in the history of color. Additionally, Philip Ball’s Bright Earth: Art and the Invention of Color (2003) provides an excellent exploration of how art, chemistry, and technology have influenced color throughout history.
