Let there light Bey.

This week, Beyoncé kicked off her Renaissance World Tour in Stockholm, Sweden, and fans went wild for her multiple costume changes throughout the 37-song set list.

Perhaps the most striking look, however, was a white bell-sleeve Anrealage coat that, when exposed to UV light that slowly traveled down her body, turned into a kaleidoscope of colors.

After the coat’s transformation, the singer coolly took it off to reveal a pearl-embellished Balmain bodysuit underneath.

Observers on social media went wild for the futuristic Fashion and her as “the queen of AI“and”BeyoncéGPT”—in a node to ChatGPT.

But there was no artificial intelligence involved in the high-tech stage hijinks.

Rather, it appeared to be the handiwork of Tokyo-based Anrealage designer Kunihiko Morinaga, who wowed fashionistas at Paris Fashion Week in March by making similar Fashion magic.

There, Morinaga integrated his light-dependent polychromic technology into faux fur, velvet, lace, knitwear, jacquards and satins, <a href="https://www.vogue.com/Fashion-shows/fall-2023-ready-to-wear/anrealage” target=”_blank” rel=”noreferrer noopener”>according to Vogue.

For the garments, he reportedly uses photosensitive fabrics and materials that change color when exposed to UV rays and direct sunlight – a once colorless bath turns into a sea of ​​vibrant patterns and colors.

Once the photochromatic areas are no longer exposed to UV rays, the ensembles return to their original color after about three minutes—allowing Beyoncé to remove the holographic coat before the colors fade.

Representatives for Anrealage did not immediately respond to The Post’s request for comment about its reported work with Beyoncé.

The luminescent look was one of 9 costume changes Beyonce made throughout the night—all of them playing on light and color.

His other stop-and-stare’ pace A Loewe cat suit included for optical illusion that made it look like hands were covering her body; an iridescent bodysuit with a matching biker jacket and detachable skirt by Georgian-born designer David Koma; and a yellow-and-black striped Mugler number that she connected to her #BeyHive fan base with an antenna headpiece in a point.
