The color khaki (UK: /ˈkɑːki/, US: /ˈkæki/) is a light shade of tan with a slight yellowish tinge. Khaki has been used by many armies around the world for uniforms and equipment, particularly in arid or desert regions, where it provides camouflage relative to sandy or dusty terrain. It has been used as a color name in English since 1848 when it was first introduced as a military uniform. In Western fashion, it is a standard color for smart casual dress trousers for civilians, which are also often called khakis.
