The diagonal axis in this painting creates momentum. The sky is not placid, but filled with marks in various directions albeit small in scale in order to emphasize the masses of the clouds. It has a narrow color range which is also in service to the main actors, the clouds, in their opposing black and white. The black cloud is in pursuit of the white, and comes close enough to cast its shadow. A clear blue stretches behind them into the distance as the white cloud bumps against the right edge of the panel in flight.
