Make Up For Ever #52L Aqua Eyes LinerMake Up For Ever #52L Aqua Eyes Liner ($19.00 for 0.04 oz.) is described as a "blue-green sheen." It's a green-tinged teal with a little undertone of blue and a subtle pearled sheen. If you have Urban Decay Covet, this may be too similar; Covet is ever-so-slightly greener and darker, while Tarina Tarantino Spark of Envy (you can see me wearing it here) is very nearly a dupe for this (at a certain angle, #52L appears to have a slightly greener tone, but it's hard to tell and would, personally, call them 100% dupes). MAC Minted is darker, greener. MAC Float on By is slightly lighter.
