The juice at the middle of Dior’s Gris — or gray — is in reality violet.

It’s the colour of the unisex fragrance, seen through its transparent bottle.

“It definitely led loads of the inspiration,” Ben Johnston said of the purple hue.

The artist is certainly one of five creatives tapped by Dior to interpret the scent in artistic endeavors. He’s joined by Andrés Reisinger, Thomas Trum, Mileece and Collectif Scale. Their oeuvres are unveiled Tuesday in a pop-up art gallery in Los Angeles, “The Grey Zone,” which shall be open to the general public from Thursday to Sunday at 8175 Melrose Avenue.

“Violet is the bottom color,” continued Johnston of his creation, “Gris” — the primary piece seen contained in the 8,000-square-foot space. Known for his daring text-based murals, he painted a 3D typography about 25 feet long and 10 feet high.

“After which I went lighter and darker, so it’s all shades of purple, violet, but some almost look black,” he added.

The artist also signed a limited-edition bottle of Gris Dior, with 200 customized copies available on the market.

Bringing a street art element inside, the “Gris Dior” letters interplay with one another on the wall.

“From afar, it’s definitely very legible,” said Johnston, who was born in Cape Town, South Africa, and is now based in Toronto. “But close, it’s loads of patterns. When you step back, you get a grasp on what it says.”

Johnston had yet to smell the fragrance, he admitted, as he was working on the installation. The inspiration got here from the colours and their nuances because it pertains to the home — including gray, the emblematic Dior shade.

“I believe color is de facto vital,” said Trum. He, too, immersed himself in the colour scheme. The artist, who lives and works within the Netherlands, is on the intersection of art and design.

“I’m currently involved in painting,” he went on. “Painting with transparent shades and having overlay and color mixing.”

He installed a wall of customized white bottles and can present a live performance throughout the opening, “Colourchanging Looping Line (Gris)” — a piece of enormous, colourful circles created with the assistance of machinery. The display will range in tones, from magenta to lavender.

“The machine is developed by an enormous American paint sprayer company that’s specialized in pumping fluids,” said Trum, who once worked as a house painter. “It’s really quite heavy, so you actually see me putting loads of effort in moving the machine over the wall.”

Meanwhile for Reisinger, the journey is digital — and rooted within the eau de parfum’s notes of chypre, citrus and floral.

“Having the scent in mind and in my brain and in my nose, and living with the scent for some time, I began to make some outputs, to create some results, some expressions,” he said of his work, hangings of canvasses in a digital gallery.

“I normally wish to exhibit them in digital canvas, that are screens,” he went on. “They’re all together to grasp the entire expression of what Gris Dior evokes to me.”

The Argentinian artist, who relies in Barcelona, Spain, explained that it captures an concept that is “not very easy to precise in words.”

It’s easier graphically, he added: “This concept that it’s completely a temporal set of fireworks…That’s how I feel after I experience Gris Dior. This concept of not having anything to do with a timeline. It’s not from the past. It’s not from the long run. It’s all at the identical time.”

For his or her part, Collectif Scale brought the fragrance to life with “Flux”; mixing visual art with music, the Parisian collective built an olfactive box that diffuses the chypre fragrance notes of Gris Dior into the room.

Mileece, the American-British biophilic technology designer, takes it further, engaging all of the senses in a separate, immersive area. Showcasing “Avant Jardin — The Essence of Fragrance is Nature,” the L.A.-based artist utilizes technology to enable biological sensations. Her goal is to attach visitors with nature.

“The purpose is, let’s orient technology toward helping us express the interconnectivity between ourselves and nature,” she said. “And, you already know, relating to perfume, obviously it comes entirely from nature.”

Working with gray and purple tones, the doorway is a moonscape followed by a walk right into a jungle with plants, flowers and sounds of nature, she explained. “In the simplest terms it’s that. But irrespective of where you’re, you’re in space.”

In her work, she uses “every avenue to assist connect people to nature and to orient our culture and society more towards the biosphere as a source of inspiration and connection and respect,” she added, noting that within the more lush area of the installation, the plants are designed to find a way to resist human touch.

“For me, the approach of the entire piece is to say, well, you already know, here we’re,” she continued. “That is where this begins. It’s not only the hand of humans, it’s really the belly of the planet that produces all of the fragrance…On this planet, we have now an environment. And we have now an environment because we have now plants. And since we have now an environment, we have now sound and all of this stuff that we take with no consideration which are so unique to us on Earth. And so the thought of the installation is to essentially bring it down into that perspective.”
