Oil Slick is a dark black with a teal micro-shimmer–it looks mostly gray-black on the lid and blended out; the shimmer so fine and sparse that it isn’t visible. The color payoff was good, though, and the texture was soft though a little drier than the other shades. bareMinerals Penthouse is a touch darker and more matte. Buxom Black Lab is similar in color but a cream product. MAC Cinderfella has more shimmer. Bobbi Brown Lava is more matte and has larger sparkle.
