Olive drab is variously described as a "dull olive-green colour" (Oxford English Dictionary);[5] "a shade of greenish-brown" (Webster's New World Dictionary);[6] "a dark gray-green" (MacMillan English dictionary); "a grayish olive to dark olive brown or olive gray" (American Heritage Dictionary);[7] or "A dull but fairly strong gray-green color" (Collins English Dictionary). It was widely used as a camouflage color for uniforms and equipment in the armed forces, particularly by the U.S. Army during the Second World War.

The first recorded use of olive drab as a color name in English was in 1892.[8] Drab is an older color name, from the middle of the 16th century. It refers to a dull light brown color, the color of cloth made from undyed homespun wool. It took its name from the old French word for cloth, drap.[5]

Olive drab was the color of the standard fighting uniform for U.S. soldiers and military vehicles during World War II. The shade used by the U.S. Army at the beginning of the war was officially called Olive Drab #3 (OD3), which was replaced in 1943 by the darker Olive Drab #7 (OD7, hex code #3C341F[9]). This was in turn replaced by the Olive Green 107 or OG-107 uniform in 1952,[10] which continued as the official combat uniform through the Vietnam War until it was replaced as the primary U.S. battle uniform in 1981 by the camouflage-patterned M81 Battle Dress Uniform, based on the ERDL pattern used by some soldiers in Vietnam which retained olive drab as one of the color swatches in the pattern.

As a solid color, it is not as effective for camouflage as multi-color patterns, though it is still used by the U.S. military to color webbing and accessories. The armies of Israel, India, Cuba, Venezuela, and Austria wear solid-color olive drab uniforms.

In the American novel A Separate Peace, Finny says to Gene, "...and in these times of war, we all see olive drab, and we all know it is the patriotic color. All others aren't about the war; they aren't patriotic."

There are many shades and variations of olive drab; one common version is defined by Federal Standard 595 in the United States.[11]
