"Coppery" suggests a warm, reddish-brown tone, similar to the color of copper metal. "Amber" is a rich, golden-brown hue with a hint of orange. "Terracotta" is a more earthy, reddish-brown color that is often used in reference to clay pottery. "Sienna" is a reddish-brown pigment named after the city of Siena in Italy. Each of these synonyms can be used in place of "tawny-colored" to describe different shades of brownish-orange.
