"One day I had painted a bunch of keys on a canvas, my bunch of keys. I didn't know what to put next to them. I needed something that would be the absolute opposite of a bunch of keys. So when I finished work I went out. I had only walked a few yard when what should I see in a shop windows? A postcard of the Mona Lisa! At once I knew that was what I needed; what could have made a greater contrast to the keys?. ..Then I also added a can of sardines. It was such a strong contrast. ."

“..a yellow square, a red and blue avenue, an Eiffel tower with a camouflaged silhouette.. ..that would all be lit up at night, instead of fireworks. .”

“The concept of Abstract painting is not a passing abstraction, good only for a few initiates, the total expression of a new generation whose necessities it experiences and to all of whose aspirations it constitutes a response.”

“I dispersed my objects in space and got them to hold together by making them radiate forwards, out of the picture. It's all an easy interplay of chords and rhythms made up of foreground and background colours, of conducting lines, of distances and of contrasts.”

“In 1942 when I was in New York, I was struck by the neon advertisements flashing all over Broadway. You are there, you talk to someone, and all of a sudden he turns blue. Then the colour fades - another one comes and turns him red or yellow. The colour – the colour of neon advertising is free; it exists in space. I wanted to do the same in my canvases.”

“I venture out to the great 'sujet'; but, I repeat, my painting always remains object painting; it starts around 1936 with 'Adam et Eve'. My figures humanise themselves further, but I always stick to the pictorial circumstance – no eloquence, no romanticism”

“Isn't it human to go beyond the limits, to grow beyond oneself, to strive toward freedom! The round is free.”
