There's no question that Jennifer Aniston is on our list of Hollywood's most beautiful celebrities. But her luxurious locks aren't the only thing that we covet.

"The Bounty Hunter" star recently attended the New York City premiere wearing lust-worthy eye makeup, commanding our attention towards her blue eyes.

Now, nobody's doubting that Aniston's eyes are gorgeously blue on their own, but one glance at her glowing orbs and we knew she had a little makeup help. Further investigation proved our theory correct: Chanel makeup artst Angela Levin played up the actress's light eye color with a reddish brown shadow found in Chanel's new Collection Essentielle de Chanel Multi-Use Make-Up Palette in Paris-New York.

Why reddish brown instead of a more mainstream taupe or walnut? "The red hue in the powder really made Jen's blue eyes pop," explained Levin.

Although it sounds counterintuitive, this type of color theory is an eye-color-brightening secret tip of many top makeup artists. In fact,enhancing your eyes with a shade that is completely opposite is makeup artist Carmindy from TLC's "What Not to Wear go-to trick from scoring peepers that glow.

"Just look on a color wheel and find the shade that's opposite your natural eye color - this tone will make your orbs look their brightest," said Carmindy.

In Aniston's case, since red is opposite green on the color wheel, any shade with a reddish tone in it -- like a copper, orange or a warm, plummy purple -- will help bring out the green tones in blue eyes, giving them a more aqua cast.
