Urban Decay Sheer Bittersweet Sheer Revolution Lipstick ($22.00 for 0.09 oz.) is described as a "sheer, bright red-purple." It's a lightly brightened, medium fuchsia magenta with cool undertones and a luminous sheen. It had semi-sheer color coverage with a lightly creamy consistency that "melts" and applies without tugging on the lips. The color could apply a bit more evenly, though the brightness of the shade distracts from some of the unevenness in application. It wore for four hours on me, and it was lightly moisturizing over time. Christian Louboutin Beaute Ronron (P, $90.00) is darker, more pigmented (90% similar).
