I went outside and saw a cloud of snow melting somewhere at the level of the seventh floor of an eight-story building. He raised his eyes and noticed the tiny figure of a roof-climbing janitor against the background of a piercing spring sky. Then I ran quickly to smear the picture until the vision disappeared. I broke the rhythm of the windows, but decided not to edit - freshness is more important than accuracy. The sky is azure, ceruleum, Prussian blue. The wall is Neapolitan yellow and yellow fawn. The windows are painted gray and ceruleum. The whitewash on the roof, squeezed straight out of the tube, dried for more than a month.
