I’m always surprised by the sheer variety you can have within a single color. You have deep, muted, cool, warm greens. You have undertones. You have finishes. It’s just incredible how even a slight alteration to a color can change it.
SIMILARITY ALERT! (I don’t think any of these are close enough to call a true dupe, but there are a couple that are quite similar.) The general feel of Korres #4 Eyeliner Pencil and Make Up For Ever #16L Aqua Eyes are very similar, but Korres is a shade or two darker and has less shimmer. MAC Jade Way Technakohl Liner and Urban Decay Mildew 24/7 Liner also seem similar at first glance, though MAC Jade Way has less black in its base and is tealer, while Urban Decay Mildew has a blacker base and leans greener. Make Up For Ever #17L Aqua Eyes and CoverGirl Green Glow Liquiline Blast are both chartreuse greens, but CoverGirl Green Glow is much darker and brighter–less gold. NARS Parrot Cay Eyeliner and Korres #12 Eyeliner Pencil are also similar, but NARS leans greener while Korres leans bluer (but they are close!).
Product Formulas/Wear: All of these wear all day long on me except NARS Eyeliners, which migrate and smudge terribly on me. I urge you to check out the NARS review and comment section, because some readers had similar experiences while others had great ones! I have not tested shu uemura’s formula at this time. CoverGirl tends to need a second pass for true color intensity. I’m not a fan of tokidoki’s Glitter Eyeliners, because their texture is rather rough from the gritty glitter, but they wear fine.
