For example, in England, we teach about Expressionism, but it is not the same in England as it is in Germany, because Expressionism is more important in the history of German art. So although it is the same history, the emphasis is different.

I greatly admired him as a teacher I didn't teach the same way as Josef Albers at all.

There was something really wonderful about being able to feel confident about doing my first exhibition in China, that people would have no trouble recognising the images and understanding my work. I also have a lot of freedom in the way I use colour, and I think that kind of freedom in colour is also understandable in every culture.

I think from an artist's point of view, everything in art, in fact everything in the world is available as material.

It's important for me to give each thing the possibility to speak and also to allow artworks speak to each other.

I look at the character of the exhibition and I treat it as I would a painting or an installation. When I did the Summer Exhibition at Royal Academy, I did it exactly as I would when making a new work.

In my early work I didn't use much colour. I had no confidence about how I could do this.
