Hailey Bieber's jet-black mani at the Academy Museum Gala — the exact OPI shade used

Hailey Bieber went glam-goth at the sixth Academy Museum Gala in Los Angeles, contrasting a bubblegum-pink Chanel column gown by Matthieu Blazy with glossy jet-black nails. Her go-to nail artist, Zola Ganzorigt, walked Vogue through the exact steps and shade behind the look.

Ganzorigt, an OPI global ambassador, first shaped Bieber's nails into a soft almond to elongate her fingers, then coated them in OPI Intelli-Gel in Black Onyx. The moody, high-shine black deliberately echoes the deep chocolate hair color Bieber debuted in September, tying the whole beauty look together.

The finish was not about layers of nail art. What makes this manicure work is restraint: one saturated shade, a precise shape, and a mirror-like gloss that stands out against pastel pink.

Bieber made it easy, she says. "[Bieber is] always down to try new things, and she's so creative when it comes to nails," Ganzorigt told Vogue. "We love creating our custom colors together by layering multiple shades, and it's always a fun time with her."

For anyone recreating the look at home, the formula is short: an almond shape, two coats of OPI Intelli-Gel in Black Onyx, and a high-gloss top coat. The payoff is a manicure that slides from an office desk to a black-tie step-and-repeat without a single change.

The black mani as a fall statement

A glossy black manicure reads like the nail-world equivalent of the little black dress: flattering and hard to get wrong. Against the bubblegum-pink gown, the dark almond tips added edge without competing with the dress.

Bieber was at the gala to celebrate cinema alongside honorees Colman Domingo and Charlize Theron and special performer Taylor Swift. Her earlier taupe nails this season already landed on fall mood boards, and this Black Onyx version is the natural next save for winter. The October 17 gala marked the museum's sixth annual celebration of film.
