Dusk is a light taupe with neutral-to-cool undertones and a pearly sheen. It had semi-opaque, buildable color coverage that applied evenly to bare skin. I found that the more I built this up, the cooler-toned it appeared--almost like the shimmer became more prominent and the reflection was cooler rather than warmer. I would not describe the shade as a duochrome, but there was more nuance to it than expected. The texture was soft, slightly dusty but blendable and easy to work with. It lasted for eight hours on me.
