"I started some colors researches in 1959 avoiding colorist; I applied the same technique to the color and the form. When I was working with colors it wasn’t to achieve a "blue hot" painting etc...I started to use not one color but all of them. I wanted them to be pure, not spoiled by black and white. I forbid myself to us any colors I didn’t choose from the start. The limited 14 colors seemed to resume all the possible variations of the chromatic mixtures." - Julio Le Parc
