Copper #4 is a darker, rusty brown with strong, warm orange undertones and a pearly sheen. The eyeshadow had rich color coverage in a single layer, which adhered well to bare skin and blended out easily. The consistency was smooth, moderately dense but not stiff to work with. It stayed on nicely for eight hours before fading noticeably.
