Couleur Additive (Caracas 1959)
This investigation is based on the radiation of color. When one plane color touches another, a darker vertical line appears at the point of contact. This virtual line in fact contributes a third color that is not in the support. By isolating this optical phenomenon, Cruz-Diez obtains the so-called "Chromatic Event Modules" responsible, in a way, of the continual transformation of color.
