This color just doesn't move me.
The NARS website describes it as a black base with cobalt shimmer, but on the nails it just registers as a denim shimmer.
This is a muted, green-toned blue: denim. Unless I'm staring really hard at it, it just looks like a vague, dusty dark color. Unfortunately though, I don't stare at my hands all day (and I'm pretty sure no one else stares at my hands either.)
It's a shame, the color would have so much more depth and impact if the shimmer were a more vibrant blue.
