YouTube confirms mixed light and dark watch page interface is an ongoing test

Mobile users recently began noticing an unusual display issue where half of the YouTube app appeared in dark mode and the other half in light mode. Initially mistaken for a software bug, a YouTube spokesperson confirmed that the split appearance is an intentional design experiment. The ongoing test affects a small group of users on both Android and iOS devices. According to the company, the experimental layout keeps the video player and comments section in Ambient mode, while recommended videos adjust to either light or dark mode depending on the user's personal preference. The goal of this experiment is to create a more immersive viewing experience for users.
