Goethe's Theory of Colours

A systematic treatise assembling detailed experiments and observations about colour, the author disputes the Newtonian explanation of the prismatic spectrum while foregrounding how ordinary perception, contrast, and gradation produce chromatic effects. He organizes material into didactic, controversial, and historical sections, examines colours in pigments, plants, and animals, and draws practical principles for painters and aesthetic judgment. Emphasis falls on how relative interactions of light, shadow, and neighbouring hues shape perceived colour more than on spectral decomposition alone, and on providing observational methods and terminologies suited to both scientific description and artistic application.
