YouTube on Monday announced a number of updates that are designed to improve the look and performance of the popular video player on desktop and on mobile devices.
An “ambient mode” changes the background color of the app in a subtle way to match the video that is playing, an effect that YouTube says is meant to draw viewers into the content. Ambient mode will be available on the web and on mobile when the dark theme is enabled.
