MAC Beluga Eyeshadow ($15.00 for 0.05 oz.) is described as a "dark charcoal with multi-dimensional pearl [with a Veluxe finish]." It's a cool-toned, dark brown with flecks of green sparkle. It had so-so color payoff, but the texture was noticeably dry and more difficult to blend out on the skin as it was stiff. Disney Cinders is warmer. MAC Mystery is lighter, more matte. MAC Black Magique is more matte. See comparison swatches.
