Urban Decay Shellshock is a very cool-toned, light-medium silver with a metallic finish. It is a discontinued eyeshadow that retails for $19.00 and contains 0.05 oz.
Shellshock is described as a "bright metallic silver." It is, indeed, a bright, metallic silver with a very strong, frosted and metallic finish. The color payoff is intense, and the texture is so buttery that it's almost creamy. I recommend applying less than you think you need, because this product binds together very well, but it also would stick and thicken over any creases/lines on my lid (so then it looked caked on). Marc Jacobs the Starlet is not as metallic. Maybelline Cool Crush is less frosted and a cream product. MAC Silver Sleet is darker. See comparison swatches.

Urban Decay’s groundbreaking new eye shadow formula. This reformulation of Urban Decay’s eye shadow features even softer, amazingly velvety texture; richer, more dense and decadent color; smoother, more uniform pigment distribution and blendability; and longer-lasting, more crease-free wear. The new line of shadows features a completely revamped assortment of shades, new textures, and a totally redesigned token compact. The secret to the new formula is Urban Decay’s Pigment Infusion System™, a vehicle for color that holds tightly to pigment and gives the formula its glide. The proprietory blend of ingredients allows color to weave itself through the formula resulting in insane color payout, color that stays on your lids, and sparkle that doesn’t fall. The amazing technology works for every shade and finish. Every Urban Decay shade is silky, blendable, and stays put.
