Urban Decay Sheer F-Bomb is a slightly cool-toned, light-medium red with a natural finish. It is a discontinued lipstick that retails for $22.00 and contains 0.09 oz.
Urban Decay Sheer F-Bomb Sheer Revolution Lipstick ($20.00 for 0.09 oz.) is described as a "sheer red." It's a muted, pinky-red with subtle cool undertones and a light shine. It looked almost warm-toned against my skin tone, but I think it will lean pinker on cooler complexions. It had semi-opaque color payoff that covered evenly for the most part and glided on easily. The color wore well for five hours on me. Burberry Oxblood No. 214 (P, $33.00) is warmer. MAC Red Necessity (LE, $20.00) is cooler-toned. Revlon Provocateur (135) (P, $8.99) is lighter. MAC Prepare for Pleasure (LE, $16.00) is less glossy. Buxom Scoundrel (P, $21.00) is brighter, cooler-toned. See comparison swatches / view dupes.
