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.

As a picture painted in yellow always radiates spiritual warmth, or as one in blue has apparently a cooling effect, so green is only boring.

Each period of a civilisation creates an art that is specific in it and which we will never see reborn. To try and revive the principles of art of past centuries can lead only to the production of stillborn works.

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

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.

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.
