I used to believe that clarity preceded work, that one arrived at the studio already knowing what needed to be done, and that painting was largely a matter of execution. Experience has taught me otherwise. I am often asked whether I plan what I am going to paint, or whether I follow a set of drawings laid out in advance. The answer is always the same. I never know what the finished work will look like. What I do know is that I am called to paint, to place colour beside colour
