Details about the upcoming iPhone 17 Pro and Pro Max continue to leak, with much of the buzz surrounding new features and specs.

However, one of the most intriguing rumours concerns the potential colour options for the iPhone 17 Pro, with leaker Majin Bu claiming that Sky Blue is a strong contender.

According to Bu, who has a history of reliable Apple leaks, sources from Apple’s supply chain have confirmed that Sky Blue is currently the frontrunner among several iPhone 17 Pro prototypes. The colour is said to be even more striking than the popular Sierra Blue introduced with the iPhone 13 Pro, offering a new level of brightness and refinement. If the leak proves accurate, Sky Blue could steal the spotlight at Apple’s expected September 2025 launch event.

What makes this rumoured launch even more notable is that Sky Blue was first seen on the M4 MacBook Air earlier this year. Apple has never before introduced a special colour for both a Mac and an iPhone in the same year. If the colour becomes a hit on the MacBook Air, Apple may look to replicate its success on the iPhone, making the iPhone 17 Pro a potential standout device in a new hue.

What to expect from the iPhone 17 Pro

Apple's Pro models have traditionally been available in standard grey shades, with one new colour introduced each year. For instance, the iPhone 15 Pro lineup included Desert Titanium as the new colour for 2023. A Sky Blue iPhone 17 Pro would certainly deviate from tradition, potentially offering a fresh look for customers seeking something unique.
