Anne Hathaway arrived at the premiere of Verity last night wearing a deep burgundy manicure that her nail artist, Mo Qin, named "cherry noir."

The shade is the darkest entry in a string of Hathaway nail moments from the past few weeks. She has worn "coconut water" nails, a sheer milky nude; a "cherry cocoa" mani in rich warm maroon; and "ruby gloss" fingertips, a classic red with an ultra-reflective finish. Cherry noir pushes the color almost to black.

The shift from warm to near-black was deliberate. "We chose a deep, dark red for Verity to bring a slightly mysterious and dramatic feeling, tying the look back to the mood of the film and her character," Qin said.

The manicure requires three products, all from Essie and all available at retail. Qin started with the Essie Strong Start Base Coat. She then applied two coats of Essie Gel Couture in Model Clicks, the polish that supplies the deep red-burgundy color. She sealed the look with the Essie Gel Couture Shiny Top Coat to lock in the shade and create the high-gloss finish visible on the red carpet.

Hathaway is not alone in moving toward darker nails as the weather cools. Dakota Johnson just stepped out with what beauty commentators have called a "brown sugar espresso" manicure. Hailey Bieber attended Paris Fashion Week with dark brown nails, a marked change from her signature glazed donut look.

The trend has practical appeal for clients. Because cherry noir is almost black, it functions like an LBD for the hands and pairs with virtually any outfit — a selling point for salons pitching seasonal color changes to indecisive clients.

For nail professionals, the formula is straightforward to reproduce in salon or at retail: one base coat, two color coats, one glossy top coat. Expect demand for deep reds and near-black burgundies to build through the cooler months as the celebrity-led dark nail cycle accelerates.
