Contact with like-minded painters, a group means a great deal to me: nothing comes in isolation. We have worked out our ideas largely by talking them through.. .One depends on one's surroundings. And so the exchange with other artists – and especially the collaboration with Lueg and Polke – matters a lot to me.

'1,024 Colours in 4 Permutations'
In order to represent all extant colour shades in one painting, I worked out a system which – starting from the three primaries, plus grey – made possible a continual subdivision (differentiation) through equal gradations. 4 x 4 = 16 x 4 = 64 x 4 = 256 x 4 = 1,024. The multiplier 4 was necessary because I wanted to keep the image size, the square size and the number of squares in a constant proportion to each other. To use more than 1,024 tones (4,096, for instance) seemed pointless, since the difference between one shade and the next would no longer have been detectable.
The arrangement of the colours on the squares was done by a random process, to obtain a diffuse, undifferentiated overall effect, combined with stimulating detail. The rigid grid precludes the generation of figurations, although with an effort these can be detected. This aspect of artificial naturalism fascinates me – as does the fact that, if I had painted all the possible permutations, light would have taken more than 400 billion years to travel from the first painting to the last. I wanted to paint four large, colourful pictures.

The first 'Colour charts' were unsystematic. They were based directly on commercial colour samples. They were still related to Pop Art. In the canvases that followed, the colours were chosen arbitrarily and drawn by chance. Then, 180 tones were mixed according to a given system and drawn by chance to make four variations of 180 tones. But after that the number 180 seemed too arbitrary to me, so I developed a system based on a number of rigorously defined tones and proportions.. .Based on mixtures of the three primary colours, along with black and white, I come up with a certain number of possible colours and, by multiplying these by two or four, I obtain a definite number of colour fields that I multiply yet again by two, etc. But the complete realization of this project demands a great deal of time and work.

Picturing things, taking a view, is what makes us human; art is making sense and giving shape to that sense. It is like the religious search for God. We are well aware that making sense and picturing are artificial, like illusion; but we can never give them up. For belief (thinking out and interpreting the present and the future) is our most important characteristic.
