Turn your neon cat-eye upside down for an unexpected-yet-cool effect. A bold red like Make Up For Ever Aqua Liner Liquid Eyeliner in Iridescent Red, $23, works well for a look like this -- just top with your favorite razor-sharp black, and be sure to ply your eyelashes with mascara.
Many of the eye looks in this slideshow are heart-stoppingly bold, and by those standards, this one's near-sedate. It's ethereal and lovely, and it's set off wonderfully by the retro red lip. Stila All Day Waterproof Smudge Stick Eye Liner in Mint Julep, $22, is a good match, in case you're looking to take this look out for a spin.

Teal Winged Liner with Blue Mascara
We've gone over a fair amount of teal eyeliner looks in this gallery -- but this look still stands out with its innovative use of blue mascara. A good blue mascara, like Benefit Cosmetics They're Real! Lengthening & Volumizing Mascara in Beyond Blue, $24, is a great tool for amping up any makeup look, especially ones that happen to incorporate technicolor eyeliner.
This look is like Brigitte Bardot-style '60s glam with an ultra-modern twist. The all-around cobalt is perfection, and it looks especially on-point with a nude lip. Try Lancome Artliner Liquid Liner, $22, in Navy, if you're looking for a similarly deep shade of blue.
