MAC Rich Core Extra Dimension Eyeshadow ($20.00 for 0.04 oz.) is described as a "dirty aubergine." It's a subtly warm-toned, burgundy with a metallic sheen. It had good color payoff both wet and dry, though the damp application was smoother and more metallic. It wore well for five and a half hours dry and eight hours damp. It seemed slightly more shimmery in this version than previously. See comparison swatches / compare dupes side-by-side.
