I recently spend some quality time with my dear friend Piero, at the National Gallery in London. The colors of this painting are much more delicate than most reproductions would have you think. This one (from The Guardian) is the closest I found on the internet. Although it is said to be unfinished, this paintings exudes freshness and light. The fine edges, connecting figure to figure and the peek-a-boo negative shapes are delightful. It’s an uplifting experience to be in its presence.
