"If you let your eye stray over a palette of colors, you experience two things. In the first place you receive a purely physical effect, the eye itself is enchanted by the beauty and other qualities of color. You experience satisfaction and delight, like a gourmet savoring a delicacy.
But then it grows calm and cool, like a finger after touching ice. These are physical sensations, limited in duration. They are superficial, too, and leave no lasting impression behind if the soul remains closed, so the physical action of color is forgotten as soon as the eye turns away.
On the other hand, as the physical coldness of ice penetrating more deeply arouses more complex feelings, and indeed a whole chain of psychological experiences, so  may also the superficial impression of color develops into an experience."- Wassily Kandinsky.
