Having a yellowish-brown, tawny, or dull orange-brown color.
From Latin 'fulvus' directly, meaning yellowish-brown. Common in English scientific literature, especially for describing animal coloration and geological samples.
If you look at old nature journals and field guides, 'fulvous' appears constantly because naturalists needed a precise color word for the browns they saw in wildlife—and it's the same word we still use today.
