NARS Seduction is a moderately warm-toned, very dark plum with a natural finish. It is a permanent blush that retails for $30.00 and contains 0.16 oz.
NARS Seduction Blush ($28.00 for 0.16 oz.) is described as "sangria." It's a deep, red wine with a very faint shimmer-sheen finish. Initially, the color in the pan reminded me a bit of NARS Outlaw, but the two aren't the same; Outlaw is more berry-hued and has golden shimmer/sheen. NARS Dolce Vita is pinker, not quite as dark. MAC Hidden Treasure is more orange, less wine/berry. MAC Stratus is warmer, a little browner in comparison. NARS G-Spot is lighter, more muted. It's also similar to NARS Grenadine, which is an eyeshadow, though the eyeshadow is redder.
