MAC Grand Galaxy Extra Dimension Eyeshadow ($20.00 for 0.04 oz.) is described as a "dirty mid-tone violet." It's a medium-dark, cool-toned purple with a metallic sheen. It is less dry and smoother than the original iteration, and it wears better as the dry base seems to come together better, though it applied slightly unevenly still. Applied dry, it is semi-opaque with a less metallic finish and lasts for five and a half hours, while damp application is mostly opaque with a bright sheen and wears for seven and a half hours.
