iOS users are left confused after the Facebook app icon mysteriously changed colour.
For years, the Facebook app has kept the white-and-blue design that the company is known for.
While there have been small tweaks over time, Facebook is one of the few major apps whose brand identity has remained largely constant on users' home screens (unlike Disney+, Netflix, Instagram, etc.), so even the smallest changes grab attention.

Why did Facebook's logo go black?
Social media users are in an uproar after the Facebook app icon on iPhones has undergone a strange colour change.
Some iOS users have been sharing reports online that the Facebook icon on their mobile devices has strangely changed from the traditional blue square with a white “F” in the middle to a black square with a blue “F.”
There's been no official word on why the color change was pushed, but the theory is that the latest update to the Facebook app accidentally pushed the dark mode logo to the social network's defaults.
Some users have also shared that their icon looks a bit different from the black icons around it, posting images of a white Facebook square with a blue “F.” This color switch also appears to be linked to Facebook's latest update, which was implemented on Thursday, August 29.
It's worth noting that this color swap isn't affecting all iPhone users, but is more prevalent among users who have installed both the latest Facebook app update and the recently released iOS 17.6.1.
The appearance of this black logo is likely linked to preparations for the full release of iOS 18 on iPhones.
One set of features coming to the latest update of Apple's mobile operating system will allow users to change the color of app icons to match their device's dark mode.
The palette swap tool is now part of iOS 18 beta 3 for users who had early access to the update, but it has had mixed results.
Apps with a consistent, simple look (such as the Facebook app) were easy to switch between, but more complex or colorful app icons failed to switch in the beta.
Facebook is yet to comment on the black app icons circulating, but the social networking giant is expected to release another small update to fix the color-switching bug.
Fans can expect dark icons to return with the release of iOS 18, which is expected to be announced in mid-September.
The Facebook app is currently available in the Apple App Store.
