I don't believe in the reality of painting, so I use different styles like clothes: it's a way to disguise myself.

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.

Maybe we didn't even have a chance. The message of American Pop Art was so powerful and so optimistic. But it was also very limited, and that led us to believe that we could somehow distance ourselves from it and communicate a different intention.

There is sorrow, but I hope one can see that it is sorrow for the people who died so young and so crazy, for nothing. I have respect for them, but also for their wishes, or for the power of their wishes. Because they tried to change the stupid things in the world.

I've never found anything to be lacking in a blurry canvas. Quite the contrary: you can see many more things in it than in a sharply focused image. A landscape painted with exactness forces you to see a determined number of clearly differentiated trees, while in a blurry canvas you can perceive as many trees as you want. The painting is more open.

My paintings are wiser than I am.

As I see it, all of them - Tachists, Action Painters, Informel artists, and the rest - are only part of an Informel movement that covers a lot of other things as well. I think there's an Informel element in Beuys, as well; but it all began with Duchamp and chance, or with Mondrian, or with the Impressionists. The Informel is the opposite of the constructional quality of classicism - the age of kings, or clearly formed hierarchies.
