Etrusque from Nars is a metallic antiqued gold with a yellow undertone. It's richly pigmented and extremely smooth to apply. I found this lasts very well on my eyelids but a primer should be used to help seal it in place for longer. This is almost identical to Bobbi Brown's limited edition chrome eyeshadow in Gold from a few years ago so you might want to check your stash before purchasing.
This eyeshadow suits a multitude of skintones and is such a great formula, I can't recommend it highly enough.
