Without form, communication stops... without form, you have everybody burbling on to themselves, whenever and however, things that no one else can understand and - rightly - no one else is interested in.

I began in 1976, with small abstract paintings that allowed me to do what I had never let myself do: put something down at random. And then, of course, I realized that it never can be random. It was all a way of opening a door for me. If I don't know what's coming - that is, if I have no hard-and-fast image, as I have with a photographic original - then arbitrary choice and chance play an important part.

Now there are no priests or philosophers left, artists are the most important people in the world.

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.

I choose depending on the way I feel; randomly, in other words. When I haven't done anything for a long time, I always start small, on paper.

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.

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.
