The arts are encroaching one upon another, and from a proper use of this encroachment will rise the art that is truly monumental.

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

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.

… lend your ears to music, open your eyes to painting, and … stop thinking! Just ask yourself whether the work has enabled you to “walk about” into a hitherto unknown world. If the answer is yes, what more do you want?

The artist must be blind to distinction between 'recognized' or 'unrecognized' conventions of form, deaf to the transitory teaching and demands of his particular age.

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.

The deeper the blue becomes, the more strongly it calls man towards the infinite, awakening in him a desire for the pure and, finally, for the supernatural The brighter it becomes, the more it loses its sound, until it turns into silent stillness and becomes white.
