It’s completely spatial. I follow Graham on that a lot. I really think that painting is about space and proportions and where things go; it’s what painting is. Form, if it isn’t the right color, it is not in the right place. And you know you can actually change the relationships a lot by changing the color a little. Yesterday, something happened in my studio. I realized that new things come to you all the time when you work in art. I had forgotten that if Graham wanted to make something slightly off-white, he used violet instead of greying it, and it’s really good. So, last night I remembered that, and the painting worked out.
