This document provides a history of color theory from ancient Greek philosophers to modern theorists. Some key points covered include Newton splitting white light into a spectrum using a prism in the 16th century, Goethe rejecting Newton's light-based theory of color in the 18th century, Munsell developing his 3-dimensional color model in the 19th century, and Bauhaus artists like Itten and Albers bringing color theory studies to the forefront and emphasizing practical exercises over rigid systems in the early 20th century. Theorists debated the nature and perception of color over centuries and numerous systems were developed to describe and order colors.
