MAC Overnight is a slightly cool-toned, dark black with a matte finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Overnight is described as a "cool black [with a Matte finish]." It's a deep black with cool undertones and a matte finish. It had decent to good color coverage, but I wish it was more blendable. The texture was a little drier and stiffer, and this translated to application as well. It did wear for eight hours, though. See comparison swatches / view dupes.
FURTHER READING: Formula Overview, which is a detailed review of the range as a whole.
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.
