A sky that replaced the weather
The whole upper band, above the far bank
London’s famous gray is gone outright. The sky is built from short and long vertical strokes of butter yellow, rose pink, pale orange, and patches of watermelon pink, a warm glow stretched across the top of the picture. It is the clearest sign that this is sensation set down, not weather recorded. Hold this against Monet’s London, where the whole subject is the fog and the changing light; here there is no fog and no hour of the day, only color.
