91Ó°ÊÓ

Over the last couple of days, Facebook users have noticed something peculiar about the app on their phone.

A Reddit thread started Thursday titled, "?" shows a blue lowercase "f" on a black background instead of a blue background with a white "f."

Some users who have their phones on dark mode chimed in with pictures of their app having a white background with the blue "f."

"The colour has become weird with the latest version. I’ve deleted and reinstalled it twice. Still hasn’t fixed issue. Any suggestions?" asked the initial post in the iOS subreddit.

91Ó°ÊÓ Network journalist Ilana Keller after downloading a Facebook app update on her iPhone, as well as iOS update 17.6.1. Keller's phone was not in dark mode.

People online wonder why the Facebook app changed colors

91Ó°ÊÓ reached out to Meta about the new color scheme on the app.

The change appears to not be in effect everywhere, as several 91Ó°ÊÓ reporters still have the original color school on their app icons.

One user on "not very demure but very irritating." Others said it looked more "" and "evil."

Some wondered the change is due to a tech update or if it is a glitch.
