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 grey the artist wrote: For me, grey is always difficult to seize hold of. It is a misty enigma between the emphatic certainties of black and white.

Grey is a nowhere space inhabited by no one. Grey is like being half-conscious of something, which is itself a nonsense, a state as vague as grey.
