Olive is a dulled, darker yellowish-green color typically seen on green olives. It can be formed by adding a little black to yellow dye or paint. As a color word in the English language, it is unexpectedly old, appearing in late Middle English
Shades of olive, such as olive drab , are frequently used for camouflage, or by the military in general.
Sometimes persons are said to be "olive-skinned", to denote shades of medium brown with small hints of yellow and green.
A similar green is caca d'oie. ("goose-shit").
