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 orange the artist wrote: Imagine a darker and darker orange until you have red, imagine a lighter and lighter orange until you have yellow - it's possible to do this even if you had never seen red or yellow before.

The French philosopher, Henri Bergson, described orange as the sensation of being 'caught between red and yellow'.

Orange points to this possibility of intuiting other realities, hidden to ordinary ways of seeing.
