NARS Super Orgasm is a slightly warm-toned, light-medium coral with a glitter finish. It is a permanent blush that retails for $30.00 and contains 0.16 oz.
NARS Super Orgasm Blush ($29.00 for 0.16 oz.) is described as a "peachy pink with gold glitter." It's a golden-shimmered, warm pink with gold glitter. It is Orgasm with glitter particles. I think that this appears slightly lighter with a stronger sheen, though. As a result, all the dupes for Orgasm apply to Super Orgasm--minus the glitter. bareMinerals The Natural High is slightly warmer in its base color (less pink). Guerlain Blush G Serie Noire is slightly deeper and pinker. Benefit Sugarbomb is much, much lighter (and sheerer). Rock & Republic Call Me is slightly less pink. Milani Dolce Pink is more frosted/sparkly. Tarte Glisten is similar--slightly darker. MAC Springsheen is also similar. This older post is a good comparison reference for coral blushes.
