Guerlain Coque d'Or #4 is a very warm-toned, medium brown with a frost finish. It is a discontinued eyeshadow.
Coque d'Or #4 is a medium brown with warm, golden undertones and a pearly sheen. The texture was firmer and stiffer in the pan, which made it harder to blend out on the skin, though it had good pigmentation. On me, it wore well for seven hours.
These shades feature matte, satin, and metallic finishes and are enriched with light pigments, reflecting light to make the eyes seem more open and brighter.
