When I told people that I was going to paint the big room magenta, many people thought that I was crazy.

You can't honour someone by copying them or trying to be exactly like them.

I have been using the computer as a work aid since the mid-90's. It is extraordinarily well suited to how I think and work and has transformed my practice. Nearly everything I have done in the past 15 years would have been impossible without it. I use the computer for drawing, composing and colour planning everything, from postage stamps to paintings to architectural-scale installations.

If things are too similar, the dialogue is not very interesting. If you put in contrast, big and small, abstract and representational, you set up the possibility of a discourse.

When I was invited to go to Wuhan, I didn't know anything about it, so I looked up the Wikipedia about Wuhan. I discovered that part of Wuhan used to be Hankou, and then I realised that my great grandmother came from Hankou. My grandmother and father were both born in Hankou. Of all the places in China, it is the most amazing place to have asked for my exhibition. I needed to go back where my family comes from!

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

I had been doing wall drawings, but they were always black and white. Then in 1993 I painted all the walls of a room to make an installation and as soon as I saw the colour on the walls, it changed my whole life.
