Urban Decay Sonic is a very warm-toned, medium-dark red with a metallic finish. It is a limited edition eyeshadow that retails for $19.00 and contains 0.05 oz.
Sonic is described as a "metallic red-copper." It's a brightened, medium-dark orange-red with warm undertones and a frosted, metallic finish. It had excellent pigmentation, and the texture was soft, smooth, and buttery, so it applied beautifully on the skin. This shade wore well for eight hours before starting to fade on me.

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.
