Burnt sienna is made by heating raw sienna—a kind of clay. Through the heating process, the yellowish-brown color of raw sienna turns into the deep hue known as burnt sienna. Its name comes from the Italian phrase “terra di Siena” or earth of Siena. Not surprisingly, it is associated with our planet, dirt, and gardening.
Combine burnt-sienna with other warm colors like oranges and yellows for an inviting color palette. For something that feels fresh and earthy, use greens and blues instead. On the other hand, use coral or salmon and whites with burnt sienna for a feminine feeling.
