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.

Color cannot stand alone.

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.

Whether the psychological effect of color is direct...or whether it is the outcome of association, is open to question. The soul being one with the body, it may well be possible that a psychological tremor generates corresponding one through association.

The artist is not a 'Sunday child' for whom everything immediately succeeds. He does not have the right to live without duty. The task that is assigned to him is painful, it is a heavy cross for him to bear.

Color is a means to exert a direct influence on the soul.
