Terracotta is a warm, muted orange-red, close to the color of fired clay, and painters usually make it too clean and bright. A little of its complement, a blue-green, muted into the mix gets the dusty, earthy quality real terracotta has, rather than a saturated coral. Burnt sienna is often most of the answer here before you reach for red at all.
