Sketch is a deep burgundy with subtle, warm undertones and a semi-matte finish. There was faint pearl in it, but it looked mostly matte in practice, especially after it was blended out. The version in this palette (which has a magnet on the back, so it really appears to be what is sold individually) is much, much more pigmented and softer with a more yielding, blendable texture compared to the last pan I purchased. It had rich color coverage that applied evenly to bare skin and lasted well for eight hours on me.
