To me, grey is the welcome and only possible equivalent for indifference, noncommitment, absence of opinion, absence of shape. But grey, like formlessness and the rest, can be real only as an idea, and so all I can do is create a colour nuance that means grey but is not it. The painting is then a mixture of grey as a fiction and grey as a visible, designated area of colour.

Painting pictures is simply the official, the daily work, the profession, and in the case of the watercolours I can sooner afford to follow my mood, my spirits.

In the beginning I tried to accommodate everything there that was somewhere between art and garbage and that somehow seemed important to me and a pity to throw away. After a while, some sheets in the Atlas acquired another value, after all - that is, it seemed to me that they could stand on their own terms, not only under the protection of the Atlas.

Cage is much more disciplined. He made chance a method and used it in constructive ways; I never did that. Everything here is a little more chaotic.

How could one be in this world without feeling dismayed by it? Even if one paints flowers and gingerbread.

There was no special event that made me decide. I had collected some photos and the idea was in the back of my mind for a long time. It was growing and growing, so finally I said, 'I must paint this.' I come from East Germany and am not a Marxist, so of course at the time I had no sympathy for the ideas, or for the ideology that these people represented. I couldn't understand, but I was still impressed. Like everyone, I was touched. It was an exceptional moment for Germany.

It's that same quality I've been talking about. It's neither contrived, nor surprising and smart, not baffling, not witty, not interesting, not cynical, it can't be planned and it probably can't even be described. It's just good.
