We all know Johann Wolfgang von Goethe (1749-1832) as the greatest of Germany’s poets (comparable to Shakespeare and Dante). But he was not only that! Goethe was also an avid amateur scientist and displayed through his careful observations and his keen, what might now be called phenomenological, mind an ability to discern the depth of the phenomenon in question. As we all learned Newton’s theory of colour formation. at school, it was very interesting for me to discover that there was a contradiction to it, a contradiction made by a poet!
Goethe, being fascinated by the colours generated from the prism conducted his own investigations and found to his great surprise that Newton’s colour theory was, if not incorrect, but rather mechanical in nature and based on an “interpretation” of the phenomenon rather than the truth as it stands.
Goethe’s Colour Wheel
His 1,400-page treatise on color Theory of Colours ( Zur Farbenlehre) was published in 1810. The work comprises three sections: i) a didactic section in which Goethe presents his own observations, ii) a polemic section in which he makes his case against Newton, and iii) a historical section. It contains some of the earliest and most accurate descriptions of phenomena such as coloured shadows, refraction, and chromatic aberration.
Goethe reformulates the topic of color in an entirely new way. Newton had viewed color as a physical problem, involving light striking objects and entering our eyes. Goethe realizes that the sensations of color reaching our brain are also shaped by our perception — by the mechanics of human vision and by the way our brains process information. Therefore, according to Goethe, what we see of an object depends upon the object, the lighting and our perception.
In fact, Goethe’s theory is being widely used today but only few of us are aware of his discovery (reminds me of a story with Nicola Tesla).
What I personally liked about this theory is the Goethes’s explanation of the pastel colours: (more…)
