Colors produce a spiritual vibration, the impression they create is important only as a step towards this vibration.

The artist is the hand that, by touching this or that key, sets the soul vibrating automatically.

Those [things] that we encounter for the first time immediately have a spiritual effect upon us. A child, for whom every object is new, experiences the world in this way: it sees light, is attracted by it, wants to grasp it, burns its finger in the process, and thus learns fear and respect for the flame.

Generally speaking, color directly influences the soul.

The sound of colors is so definite that it would be hard to find anyone who would express bright yellow with bass notes or dark lake with treble.

Of all the arts, abstract painting is the most difficult. It demands that you know how to draw well, that you have a heightened sensitivity for composition and for colors, and that you be a true poet. This last is essential.

The artist must have something to say, for mastery over form is not his goal but rather the adapting of form to its inner meaning.
