The year is always correct, also the month, only the day can be another. But that occurs to me only in the moment of writing it down.

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.

I was a student, and as such you generally rely on prior models of how to make art, but these were not satisfying. Then I discovered in photos what had been missing in paintings; namely that they make a terrific variety of statements and have great substance. That is what I wanted to convey to paintings and apply to it.

I'm never really sure what that word means, but however inaccurately I use it, 'classical' was always my ideal, as long as I can remember, and something of that has always stayed with me, to this day. Of course, there were difficulties, because in comparison to my ideal, I didn't even come close.

I never worked at painting as if it were a job; it was always out of interest or for fun, a desire to try something.

Since there is no such thing as absolute rightness and truth, we always pursue the artificial, leading, human truth. We judge and make a truth that excludes other truths. Art plays a formative part in this manufacture of truth.

I originally came from Dresden, where Socialist Realism prevailed. Konrad Lueg and I came up with it, for the most part ironically, since I now live in capitalism. It was certainly 'realism', but in another form - the capitalist form, as it were. It wasn't meant that seriously. It was more a slogan for that particular Happening at a furniture store.
