MAC Earthshine Mineralize Skinfinish ($29.00 for 0.24 oz.) is described as a “tarnished bronze with gold pearl and pink reflects.” It’s a red-toned brown with burgundy and gold shimmer. The powder is composed of a dirty gold, peach-orange, and burgundy. I don’t have Metal Rock, but it might be similar to this (so check your own stash!)–from what I can recall, Metal Rock is browner. MAC Warm Blend has a similar-colored strip in the middle, though it’s not as red-toned. MAC Pressed Amber is much lighter and browner, less red-toned.
