Mondrian expressed that �if color represents meaning and expression it has to be a universal, general meaning formulated in every separated color and specified in the relation unity of image. Unity and relationship are the determinants in the roots of the meaning in color. Yet, he offers no opinion on the question of whether color carries an inner meaning of its own. He needed to make the universal visible; this fact forced him to keep available the possibilities of the pure, saturated color; then, he used it in all of his works.
