THEORY OF COLOURS
Though hardly a work of science, Goethe’s Theory of Colours stands as an absorbing account of the philosophy and artistic experience of colour, bridging the intuitive and the visceral in a way that, more than two hundred years later, continues to intrigue.
One of Goethe’s most radical points was a refutation of Newton’s ideas about the color spectrum, suggesting instead that darkness is an active ingredient rather than the mere passive absence of light.
…light and darkness, brightness and obscurity, or if a more general expression is preferred, light and its absence, are necessary to the production of colour… Colour itself is a degree of darkness.
