MAC Evening Grey Extra Dimension Eyeshadow ($20.00 for 0.04 oz.) is described as a "steel silver." It's a medium silver gray with a frosted, slightly metallic, finish. It had a slightly drier and looser texture, so this is one that really works better damp, as the powder comes together and goes on more smoothly as a result. It had semi-opaque coverage dry and mostly opaque pigmentation damp. Dry, it lasted for five hours; damp, it lasted for seven hours. See comparison swatches / compare dupes side-by-side.
