MAC Hidden Treasure is a very warm-toned, dark red with a luminous finish. It is a limited edition blush that retails for $24.00 and contains 0.21 oz.
MAC Hidden Treasure Blush ($20.00 for 0.21 oz.) is described as a "rich burnt red." It has a velvet finish, according to the back, though the press release had originally listed it as a satin. The color is a dark rusted red with a very subtle sheen, no detectable shimmer or the like, and a warm, red-orange undertone. MAC Ring of Saturn is lighter and has more of a golden sheen--it would still look very similar if used lightly. Tom Ford Savage is lighter, more muted, less red. NARS Liberte is more orange, less red.
