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.

My landscapes are not only beautiful, or nostalgic, with a Romantic or classical suggestion of lost Paradises, but above all 'untruthful.' By 'untruthful,' I mean the glorifying way we look at Nature. Nature, which in all its forms is always against us, because it knows no meaning, no pity, no sympathy, because it knows nothing and is absolutely mindless, the total antithesis of ourselves.

Grey. It makes no statement whatever; it evokes neither feelings nor associations: it is really neither visible nor invisible. Its inconspicuousness gives it the capacity to mediate, to make visible, in a positively illusionistic way, like a photograph. It has the capacity that no other colour has, to make 'nothing' visible.

Contact with like-minded painters - a group means a great deal to me: nothing comes in isolation. We have worked out our ideas largely by talking them through. Shutting myself away in the country, for instance, would do nothing for me. One depends on one's surroundings. And so the exchange with other artists - and especially the collaboration with Lueg and Polke - matters a lot to me: it is part of the input that I need.

The smudging makes the paintings a bit more complete. When they're not blurred, so many details seem wrong, and the whole thing is wrong too. Then smudging can help make the painting invincible, surreal, more enigmatic - that's how easy it is.

A lot of different things had to come together over the years, accumulated experiences of a general and personal nature, before the idea and the decision were developed and then carried out.

As a matter of fact, it was only through the dealer Fred Jahn that I succeeded in overcoming my reservation about the works on paper and exhibiting them. Added to this, of course, was the fact that after ten years I could see the watercolours in a different light, and in conjunction with pictures painted afterwards, they had at least become more comprehensible to me.
