MUCH ADO ABOUT BLUE: Legend has it that about a century ago, French couturier Jeanne Lanvin was so transfixed by the heavenly blues in Fra Angelico’s frescoes in Florence that she gazed at them until her neck ached.

At which point she made blue a signature color, applying it to dresses, accessories, perfume bottles and her gobsmacking bedroom, a permanent attraction at the Musée des Arts Décoratifs in Paris (which is celebrating the centenary of Art Deco this year, incidentally).

According to Lanvin, its founder developed 23 shades of blue at her dye factory in Nanterre, one of which was applied to the curtains and seats at the Daunou theater in Paris, one of many decoration projects done in concert with Armand-Albert Rateau.

Now the house has settled on a new proprietary color, dubbed Lanvin Blue. It debuts Monday on revamped carrier bags and boxes, and it will feature in creative director Peter Copping’s sophomore collection for the house, scheduled to hit the runway on Sept. 30 during Paris Fashion Week. (He already incorporated Lanvin Blue for the lining and trims of certain fall 2025 accessories.)

Why the new blue?

“These are essential ingredients in the actual client experience, where we place a great deal of attention,” according to Siddhartha Shukla, deputy general manager of Lanvin. “We have been careful and deliberate in reimagining and redefining every gesture that signals a new direction for Lanvin.”

The fashion house had invited M/M Paris to redesign its logo in 2022, and the new color is the creative agency’s latest tweak.

In developing proprietary colors and in-house embroideries, the late founder set a template that Shukla is exalting.

“We are simply reviving this narrative, centered around Lanvin Blue which so visibly characterized her work across domains, from fashion to interiors,” he said, insisting that “color at Lanvin is not a gimmick or opportunistic marketing tactic — it is fundamental to the house ethic and our artistic expression.”

Meanwhile, Copping said blue’s “tranquility and serenity hold a special resonance for me. At Lanvin, a house where blue is woven into its very DNA, I am thrilled to embrace this color and weave it into my collections.”

For spring 2026, this color “steps into the spotlight, infusing both the silhouettes and also the show space with its presence.”
