Die Chromatika is a new psychological theory of colour for the 21st Century, created by the artist in response to Goethe's 'Theory of Colours' and Rudolf Steiner's writings on colour.

Of violet the artist wrote: I once owned a little watercolour of Las Palmas in Gran Canaria. In my journal I described the sky above the town as filled with 'ominous violet (violent) storm clouds.'

This correlation between 'violet' and 'violent' is about more than the similarity of the English words. I think it's no coincidence that bruises are violet too.
