✅ Russet describes something that is one of a range of brown-toned, autumnal colors, including yellowish and reddish browns and light browns that are neither red nor yellow (Russet leaves covered the street).

✅ Titian describes things that are a reddish or golden brown (She had flowing titian hair).

✅ While russet derives from an old French word related to “red,” titian is named after an Italian painter who often painted red-haired women. Describing something as titian suggests a warm, romantic, glowing tone, as the paintings of Titian exude.
