"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."

“As far as the surface is concerned – oil on canvas, conventionally applied – my pictures have little to do with the original photograph. They are totally painting . On the other hand, they are so like the photograph that the thing that distinguished the photograph from all other pictures remains intact.”

“I am primarily painting from photographs these days , in a sense this is a stylistic problem, the form is naturalistic, even though the photograph is not nature at all but a prefabricated product , I do not have to intervene artistically with style, since the stylization contributes only under very particular circumstances toward clarifying and intensifying an object or a subject , it leads to an unmotivated artificiality, an untouchable formalist taboo.”

“To talk about paintings is not only difficult but perhaps pointless, too. You can only express in words what words are capable of expressing, what language can communicate. Painting has nothing to do with that.. .Painting is another form of thinking.”

“We could really just speak about painting. The main thing was about the surface of color or the proportion of color. It was impossible for me to talk to Sigmar Polke about the opacity of color. With Palermo, yes. We supported each other, we comforted each other a little bit. We thought this really could not be true that everything was supposed to be over , and our art was not relevant.”

“The first impulse towards painting, or toward art in general, stems from the need to communicate, the effort to fix one's own vision, to deal with appearances Without this, all work would be pointless and unjustified, like Art for Art's Sake.”

“As a role that everyone has. I would like to try to understand what is. We know very little, and I am trying to do it by creating analogies. Almost every work of art is an analogy. When I make a representation of something, this too is an analogy to what exists; I make an effort to get a grip on the thing by depicting it. I prefer to steer clear of anything aesthetic, so as not to set obstacles in my own way and not to have the problem of people saying: 'Ah, yes, that's how he sees the world, that's his interpretation.”
