Shading is more like copying. And certainly I do copy, but I'm making drawings, and I'm not trying to make them with the shading.

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

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.

Shape and color are my two strong things. And by doing this, drawing plants has always led me into my paintings and my sculptures.

My forms are geometric, but they don't interact in a geometric sense. They're just forms that exist everywhere, even if you don't see them.

All my paintings are usually done in drawing form, very small. I make notations in drawings first, and then I make a collage for color. But drawing is always my notation.

The most pleasurable thing in the world, for me, is to see something and then translate how I see it.
