MAC Shell Peach Eyeshadow ($18.00 for 0.05 oz.) is a light-medium, peachy coral with moderate, warm undertones and a satin finish. It had sheer color coverage in the best case scenario; it was marginally better over an eyeshadow primer, but it was more of a subtle, diffusing shade than a practical all-over-the-lid kind of eyeshadow.
The consistency was ridiculously powdery and dry, so there was excess kicked up in the pan but also fallout during application. There were signs of fading after six hours of wear (from what I could tell).

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.
