Wayne Thiebaud’s interest in investigating the properties of each medium lead him to create a series of works of the same subject using different techniques. In the pictured watercolor of Nine Jelly Apples (1964) he used a wide range of pink and purple hues to suggest the luminous surface of the confection. In the black ink version, he relied instead on the vivid dark and light contrast to emphasize shininess. In the pencil version, however, the exacting precision suggests the brittle surface of hardened sugar.
