Everything that is dead quivers. Not only the things of poetry, stars, moon, wood, flowers, but even a white trouser button glittering out of a puddle in the street... Everything has a secret soul, which is silent more often than it speaks.

Absolute green is the most restful color, lacking any undertone of joy, grief, or passion. On exhausted men this restfulness has a beneficial effect, but after a time it becomes tedious.

Color is the keyboard. The eye is the hammer. The soul is the piano, with its many strings.

Each color lives by its mysterious life.

The more abstract is form, the more clear and direct its appeal.

A parallel between color and music can only be relative – just as a violin can give warm shades of tone, so yellow has shades, which can be expressed by various instruments.

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.
