Color is the keyboard, the eyes are the harmonies, the soul is the piano with many strings. The artist is the hand that plays, touching one key or another, to cause vibrations in the soul.
…
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.
~ Wassily Kandinsky
