MAC Thunder and Rain #1 is a very cool-toned, dark gray with a pearl finish. It is a limited edition eyeshadow that retails for $21.00 and contains 0.06 oz.
Thunder and Rain #1 is a cool-toned, medium-dark gray with apearly finish. It had semi-sheer color payoff applied dry, and when applied damp, it was slightly improved but not by much. The eyeshadow lasted well for six and a half hours, and then it started to fade. MAC Diesel is a touch darker. MAC Smokeluxe #4 is similar, more metallic. Urban Decay Asphalt is darker. Urban Decay Ace is darker. Giorgio Armani #21 is more frosted. See comparison swatches.
The Mineralize Eyeshadow formula is supposed to have "low-to-medium coverage" when applied dry and "more intense coverage and color" when used wet. Most shades have color payoff that is true to the brand's description: semi-sheer to semi-opaque when used dry and semi-opaque to opaque when used with a dampened brush. I tend to find that they apply more smoothly and evenly with a more metallic finish with a dampened brush as well. Some shades can be a little too dry or dusty and do not apply as well with a dry brush. The wear is typically a bit less than average on me--six to seven hours.
