Like Brick Brown, Rust is on the cusp between red and brown. The grey elements in this colour temper its intensity in comparison to Brick Brown, for example. Rust is the colour of autumn as we move into winter and its barren, dusty landscapes after the initial blaze of seasonal colour. It pairs nicely with all kinds of Reds.
Rust derives its name from russet, a coarse woollen cloth of brown or grey colour worn by the lower classes in the Middle Ages.
