Truth moment: I have about a million (OK, 87) nail polishes on a rack under my bathroom sink. I wear about three of them on a regular basis. Blame it on my incessant nail biting or my fear of being too trendy, but that's the truth. And when it comes to pairing polishes for my DIY mani-pedi, it's a process. I question everything -- "What if it's too dark? Does this work for the office?"

So I reached out to nail guru Jin Soon, Essie manicurist Michelle Saunders, Scotch Naturals founder Ginny Cardenas, Red Carpet Manicure nail technician Candace Szpiech and the founders of Hoopla, Megan Thornberry and Molly Maxwell. I asked them to weigh in on some of the hottest mani-pedi color combos to try this season. Soon suggests some basic guidelines to follow:

• Choose shades that flatter your skin tone.
• Create contrast. Nothing looks more askew than two colors that are only slightly different -- it makes your color choice look like an accident.
• Don't choose two super-loud colors. Painting neon shades on toes and fingers is too much.

Think you've got it? Check out the color combos they're raving about now.

There's a reason pastel colors are spring staples. A bold berry shade on your toes, like Envy by Michael Kors, makes a statement when paired with a pale yellow color, like NARS Sharks, on your nails.

"Evocative of painted Easter Eggs, the purple-and-yellow combination is one of the first reminders that spring has sprung," says Soon.

Staying within a color family is a smart move when pairing your mani-pedi shades. A lighter shade of pink like Revlon ColorStay Longwear nail polish in Café Pink on your hands and a brighter pink like Jin Soon Cherry Berry on toes is complementary without being matchy-matchy.

"Both colors are so classically iconic and feminine that they stand on their own," says Soon.

For instant trendsetter status, try Essie nail polish in Butler Please on your toes and Jin Soon Kookie White on your nails. It's a daring match that won't go unnoticed.

"We have seen many hues of blue this fashion season in garments and accessories so why not add some blue to your nails?" says Saunders. Soon adds, "The highly contrasting graphic colors make this combination cool and unexpected."

If you want to let your toes have all the fun, paint a sheer pink color like OPI nail lacquer in Are You Calling Me a Lyre? on hands, which will make a vibrant hue like Red My Lips by Sally Hansen Complete Salon Manicure stand out on toenails.

"This is what I call a classy classic, which is why it is the most popular match I see in my salons," says Soon. "It works well on the beach or at dinner, [especially] with tanned limbs."
