I love how smooth the UD shadows are.
Urban Decay makes a nice variety of shades.
They have a collection of matte shadows and pretty much all of them are very wearable. Electric, Chronic, Puple Haze, and Narcotic are the only bright colors from their matte collection.
From their regular eyeshadows, Baked, Half baked, Twice baked, Blunt,Blaze, Jones, Roach, X, Stray Dog,Toasted, Chopper, Sin and Sellout look very nice.
Then there is also their Deluxe line of shadows which comes in really fun packaging. Honey, Scratch, Shag, and Underground are nice. The UD Deluxe shadow box comes with all 4 of those shades plus 5 of the other Deluxe shadows in brighter colors, and it pairs really well with the shadows from the Book of Shadows.
For little pops of color, the UD 24/7 liner pencils are great. You can get a travel set of 5 for a very reasonable price and they stay on really well. HTH
