On Vision and Colors; Color Sphere: by Arthur Schopenhauer and Color Sphere by Philipp Otto Runge

Synopsis

During the first two decades of the nineteenth century two of the most significant theoretical works on color since Leonardo da Vinci's Trattato della Pittura were written and published in Germany: Arthur Schopenhauer's On Vision and Colors and Philipp Otto Runge's Color Sphere. For Schopenhauer vision is wholly subjective in nature and characterized by processes that cross over into the territory of philosophy. Runge's Color Sphere and essay The Duality of Color contained one of the first attempts to depict a comprehensive and harmonious color system in three dimensions.
