Turning to the colour-classification methodology: The starting point are the four pure colours red, yellow, green and blue; their in-between shades and scales of brightness result in colour schemes containing 16, 64, 256 and 1,024 shades. More colours would be pointless because it wouldn't be possible to distinguish between them clearly.

My paintings are wiser than I am.

But I have a problem with the term 'light'. I never in my life knew what to do with that. I know that people have mentioned on some occasions that 'Richter is all about light', and that 'the paintings have a special light', and I never knew what they were talking about. I was never interested in light. Light is there and you turn it on or you turn it off, with sun or without sun. I don't know what the 'problematic of light' is. I take it as a metaphor for a different quality, which is similarly difficult to describe. Good.

I wanted to make it as anonymous as a photo. But it was perhaps also the wish for perfection, the unapproachable, which then means loss of immediacy. Something is missing then, though; that is why I gave that up.

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 (whatever that may mean). On the other hand, they are so like the photograph that the thing that distinguished the photograph from all other pictures remains intact.

Painting is the making of an analogy for something non-visual and incomprehensible - giving it form and bringing it within reach. And that is why good paintings are incomprehensible. Creating the incomprehensible has absolutely nothing to do with turning out any old bunkum, because bunkum is always comprehensible.

I remember that I felt I had to avoid all these sensational photos, the hanged woman, the man who shot himself, and so forth. I collected a great deal of material, including a number of banal, irrelevant photos, and then in the course of my work I came back to the very pictures I had actually wanted to avoid, which summed up the various stories.
