When we describe a process, or make out an invoice, or photograph a tree, we create models; without them we would know nothing of reality and would b… - Gerhard Richter

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.

We [Richter and w:Blinky Palermo ] 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 ['painting' as an expression of art, in the 1970's). Art had to be relevant [in the 1970's], and our art was not relevant.

This one is too elegant, too shiny, like jewelry. It seeks applause. This is clear to me, but difficult to explain, which is what makes abstraction so fascinating. In one sense, abstract art is absolutely nothing, stupid. In 100 years, maybe people will just think it's garbage. But somehow we see something in it; we have a sense of quality. [searching for an illustration of his point, Richter leafs through a catalog to find some of his 'gray monochromes']. I was doing these [monochromes] when I was getting divorced. When you feel totally empty, you do this - but then I saw that one picture was actually better than another. Both were miserable, but the difference was interesting. I loved this: that there must be something, some higher faculty, some progressive sensibility that we find in abstraction. But it is impossible to describe.
