The good news: There are a bajillion nail polishes out there. The bad news: Not all of them are going to look amazing on you. That beige nude polish may look fabulous on your friend but completely wash out your complexion. Knowing a few insider tricks can help you cut through the clutter and pick the most flattering colors for you. We asked celebrity manicurist Casey Herman, who works with Lupita Nyong'o, for her top tips when picking flattering pink, red and neutral nail polish colors for dark skin tones.

1. Look on the Bright Side
Picking flattering red and pink polishes can be tricky. Herman suggests looking for pinks that have yellow undertones (think: coral, not bubblegum) and reds that have a bit of orange in them. 2. Build It Up
Sheer polishes, especially red and pinks, can look washed out on dark skin. To make the color pop, try Herman's trick: Swap your usual clear base coat with one that has a beige tint to build up the boldness of your polish pick. 3. Steer Clear of Slate
Picking nude polishes can be just as frustrating as picking a nude lipstick. Make it easier by staying away from nudes that have a white or gray base. "It will make your skin look dull," says Herman. Instead, pick nudes with a brown or yellow base, she suggests. 4. Think Pink
When done correctly, pale nude nail polish can look feminine and chic. But if it makes your nails look naturally blah instead of naturally beautiful, ditch your beige-y nude and switch to sheer pink, says Herman. "It won't make your nails look an unhealthy pale."
