Urban Decay 501 is a moderately cool-toned, dark blue with a sparkle finish. It is a limited edition eyeshadow that retails for $19.00 and contains 0.05 oz.
501 is described as a "deep metallic blue with copper micro-glitter." It's a medium-dark, cobalt blue with a pearly sheen and fine copper sparkle. As you might expect, the sparkly bits don't bind well with the underlying color, so they get lost in the brush or drop on the lid when applying, unless you pack it on over a tacky base. The texture was slightly dry and harder to blend out. This one stained my lids slightly for about 36 hours after application, and it also did so even with a primer (UDPP). The color wore well for eight and a half hours before fading. Urban Decay Danger (LE, $19.00) is darker, brighter, cooler (90% similar). LORAC Cobalt (LE, $19.00) is more shimmery (90% similar).
