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.
