*Bloomberg*'s Mark Gurman has disputed the authenticity of iPhone Ultra renders shared by the usually reliable leaker Evan Blass on X (Twitter). The images show the unreleased foldable iPhone in not just the rumored space gray and white colors, but also in a striking red.

"Hearing these renders came from Xiaomi," wrote Gurman, commenting on Blass's post. "This isn't a legitimate look at the foldable iPhone, which also doesn't come in red or green. Just renders made by Xiaomi for some reason. Carry on."

Apple is said to be planning to "stay away from fun colors" and stick to more traditional space gray/black and silver/white finishes for the book-style foldable iPhone. One rumor has described the darker color as a shade of indigo rather than black.

Apple will hold its annual iPhone event on Wednesday, September 9 at the Apple Park campus in Cupertino, California, where the company is expected to debut the foldable alongside new iPhone 18 Pro models. This year's tagline is "Surprise and shine."
