Mark Rothko's No. 14 at San Francisco Museum of Modern Art

It all happens within a benign universe: A fiery orange rests above a deep, alluring blue.

Two movements: one in, the other out. A deep and ponderous blue, and the fiery orange of action, speech, life. The latter rests securely on the former, the former draws energy and life from the latter.

It's how a world gets created.
