I believe people have to be open to what's happening when they're alive.

The paintings to me are always canvas, sculpture has always been metal, though I have made sculpture in wood also.

My drawings have to be quick. If they don't happen in 20 minutes or a half hour, then they're no good.

All my work begins with drawings. I don’t labor over my drawings. I want to get freedom in the line. I like to be able to get swift curves in the plant drawings that are usually drawn in five to ten minutes.

The form of my painting is the content. My work is made of single or multiple panels: rectangle, curved, or square. I am less interested in marks on the panels than the 'presence' of the panels themselves. In Red Yellow Blue III the square panels present color. It was made to exist forever in the present; it is an idea and can be repeated anytime in the future.

I have worked to free shape from its ground, and then to work the shape so that it has a definite relationship to the space around it; so that it has a clarity and a measure within itself of its parts (angles, curves, edges and mass); and so that, with color and tonality, the shape finds its own space and always demands its freedom and separateness.

I did not want windows, only skylights. I chose my painting wall as it has the best morning light.
