Ochreous

Ochreous is an adjective used to describe something that has the color of ochre, or is tinged with ochre. Ochre itself is a natural earth pigment containing hydrated iron oxide. The color of ochre can vary widely, but it is typically a shade of yellow, brown, or reddish-brown. Therefore, when something is described as ochreous, it suggests a warm, earthy tone.

The term can be applied to a variety of subjects. In geology, rocks or soil might be described as ochreous if they exhibit this characteristic color, often indicating the presence of iron in their composition. In biology, the plumage of a bird, the fur of an animal, or even the coloration of certain fungi might be referred to as ochreous if they possess this earthy hue. Similarly, in art and design, an ochreous color palette would involve shades reminiscent of natural earth pigments. The word implies a natural, often muted, and earthy quality of color.
