This sienna is a natural orange-brown earth pigment imported from Italy.
Use this and the 'limited edition' sienna's with the same method and purpose as plain Burnt Sienna. Many artists prefer Italian Burnt Sienna over others. Perhaps it is the subtle semi-transparent quality of Italian Burnt Sienna which has such appeal.
Balance a super-opaque such as Indian Red or Cadmium against super transparent Quinacridone Gold or Burnt Orange, then incorporate Italian Burnt Sienna to unify autumn landscapes or close-up leaf studies, as well as to render weathered slate and old brick.
