For something a little more subtle than say candy-cane stripes—or chunky glitter gradient nails—but no less festive, try a marbled mani instead. It’s easier to do than you think (really, we tried it) and can be worn through the New Year.
Apply basecoat and one coat of an opaque neutral polish like OPI Nail Lacquer in Alpine Snow ($9, birchbox.com) so you get an even canvas for marbling. Let dry.
Using two to three accent colors, place a few dots of each polish onto your nail, letting them overlap a little. While the polish is still wet, take a nail striping brush like Winning Nails Thin Red Sable Nail Art Striping Brush ($10, sallybeauty.com) and swirl it gently between the dots until they are connected across your nail bed. Repeat on each finger.
Dry longer than usual to ensure no streaks (which will mess up the marble effect) and finish with a glossy topcoat like Dior Gel Coat ($27, sephora.com).
