Johann Wolfgang von Goethe's "Theory of Colours" stands as a monumental work that challenges Isaac Newton's established optical theories. Published in 1810, Goethe presents a phenomenological approach to color, arguing that colors arise from the interplay of light and darkness, rather than being mere components of white light. His treatise delves into the psychological and physiological aspects of color perception, exploring how colors affect human emotions and experiences. This influential text, while scientifically controversial in its time, profoundly impacted artists, philosophers, and scientists alike, offering a rich, holistic perspective on the nature of color and its profound connection to human consciousness.
