My work is about structure. It has never been a reaction to Abstract E — Ellsworth Kelly

"Making art has first of all to do with honesty. My first lesson was to see objectively, to erase all meaning of the thing seen. Then only, could the real meaning of it be understood and felt."

"When I want to do a painting with one colour overlapping another, it has to be a real overlap, not a depicted overlap. I didnt 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. Its the only one I ever did using actual dyed fabric of ready-made colours, which moves the painting into the realm of real objects."

"In Europe at the beginning of the twentieth century, the Fauves – Matisse, Derain – were using bright colours in their full intensity, which continued with Kandinsky, Malevich, Kirchner, Léger and Mondrian. They employed all the colours of the spectrum. In the 1940s and 1950s the majority of the Abstract Expressionists in New York rebelled against this European use of colour and mostly used mixed colours. That is, the Abstract Expressionists did use bright colours sometimes, but they tended to paint wet-on-wet, which muddled their hues. As Matisse would say, a small patch of any one colour is far less intense than a large one of the same colour. I returned in 1954 [from Paris] to New York and showed paintings done in France at the Betty Parsons Gallery in 1956 with bright colours that wouldn’t really be used until the Pop artists in the 1960s. My idea of using colour at its full intensity, which began with Colors for a Large Wall, hasn’t changed in the 60 years that I’ve been painting."

"I felt that everything is beautiful, but [not?] that which man tries intentionally to make beautiful; that the work of an ordinary bricklayer is more valid than the artwork of all but a very few artists."

"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, not a photo as in the postcards [collages], and therefore a contrast of the traditional painting and a presentation of literal space on top of depicted space."

"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."
