No more sufficient, in the psychic sphere, is the theory of
association. Generally speaking, colour is a power which directly
influences the soul. Colour is the keyboard, the eyes are the
hammers, the soul is the piano with many strings. The artist is
the hand which plays, touching one key or another, to cause
vibrations in the soul.

IT IS EVIDENT THEREFORE THAT COLOUR HARMONY MUST REST ONLY ON A
CORRESPONDING VIBRATION IN THE HUMAN SOUL; AND THIS IS ONE OF THE
GUIDING PRINCIPLES OF THE INNER NEED.

[Footnote: The phrase "inner need" (innere Notwendigkeit) means
primarily the impulse felt by the artist for spiritual
expression. Kandinsky is apt, however, to use the phrase
sometimes to mean not only the hunger for spiritual expression,
but also the actual expression itself.--M.T.H.S.]



VI. THE LANGUAGE OF FORM AND COLOUR



The man that hath no music in himself, Nor is not mov'd with
concord of sweet sounds, Is fit for treasons, stratagems, and
spoils; The motions of his spirit are dull as night, And his
affections dark as Erebus: Let no such man be trusted. Mark the
music. (The Merchant of Venice, Act v, Scene I.)
