Nail tech Josephine Allen of the Samuel Shriqui Salon in New York City shows Allure Spa readers how to choose the right polish to match skin tone.

For fair skin, Allen says a blue-based burgundy or a sheer pink that's not too yellow or white will tone down the redness found on light skin. She recommends OPI Sweet Heart and Essie Lacy Not Racy.

For medium skin, she says, "Both dusty rose and bright red with a hint of blue complement the yellowness of miedum skin tones." She likes Rimmel London Ash Rose and Lippmann Collection My Old Flame.

For dark skin, Allen suggests "deep wines verging on brown" and "bright orange-based red with no shimmer." She suggests OPI A Oui Bit of Red and Rescue Beauty Lounge Atame.
