YouTube’s rainbow progress bar is a visual representation of the progress of a video being watched. It is typically displayed at the bottom of the video player, and it changes color as the video progresses. The rainbow bar can be customized to match the branding of a channel, and it can also be used to promote special events or campaigns.
The rainbow progress bar was first introduced in 2012, and it has since become a standard feature of the YouTube video player. It is a simple but effective way to track the progress of a video, and it can also be used to add a touch of personality to a channel.
