MAC Blue Black is a very cool-toned, dark blue with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Blue Black is a dark, navy blue with a black base and lighter, brighter blue pearl. The color payoff was good--just shy of full coverage--and applied evenly to the lid. I felt like this shade looked more satin by the time I blended it out, as the shimmer did not seem as present or as reflective. It wore well for eight hours on me before fading.

These saturated shadows in neutral and metallic shades and multiple finishes stay on all day long with non-creasing, eight-hour wear. The result: potent colour payoff that applies evenly, blends well and can be used wet or dry.
