NARS Shatter Powermatte Lip Luster Pigment ($26.00 for 0.18 oz.) is a medium brown with warm undertones and a pale, bronze sheen. It had semi-opaque pigmentation, which could be made opaque with a second layer (just make sure to let the first layer dry completely before adding more product). It had a lightweight consistency that was quite fluid but shy of being watery, so it was manageable along the edges of my lips without too much worry. The color stayed on well for five hours and was non-drying.
