In winter in Tangier, the rain often ends late in the afternoon: when it does, the dark blue clouds split open to spill out a pinkish beige on to the previously white walls of the Casbah, the shadows turning cool green in contrast. Loti was correct in describing Tangier as the white city. But its whiteness is that of a canvas waiting to receive colour — blue, pink, and green — that nature provides.
