Like the postcard collages, the colors are shapes in a landscape. In this case [his collage 'Napoleon at Würtsburg'] it is a painting of a landscape,… - Ellsworth Kelly

In my painting, negative space is never arbitrary. (I believe lithographs to be colored marks printed on a ground – the paper and the measure of the ground and the marks are to be considered of equal importance). In my painting, the painting is the subject rather than the subject the painting.

My work is about structure. It has never been a reaction to Abstract Expressionism. I saw the Abstract Expressionists for the first time in 1954. My line of influence has been the 'structure' of the things I liked: French Romanesque architecture, Byzantine, Egyptian and Oriental art, Van Gogh, Cézanne, Monet, Klee, Picasso, Beckman..

When I want to do a painting with one colour overlapping another, it has to be a real overlap, not a depicted overlap. I didn't want to paint an overlap, meaning that it would be a deception or illusion. I no longer wanted to depict space, but to make a work that existed in literal space. Thus, my recent works are one canvas as a relief over another canvas. Another important example of a panel painting that explores the idea of the mural was Red Yellow Blue White 1952. It's the only one I ever did using actual dyed fabric of ready-made colours, which moves the painting into the realm of real objects.
