The term "olive" refers to the color, usually describing a yellowish-green shade similar to that of olives. It derives from the Old French word "olive" and Latin word "oliva", both of which mean "olive tree" or "olive".
"Browns" refers to the color brown. It comes from the Old English word "brūn", which meant "dark, dusky" or "to become brown".
