Here’s how to turn on YouTube dark mode on the web
Of course, the world of mobile OS has already seen the introduction of a dark mode in YouTube and we’ll discuss how to enable that later on. But not every YouTube user has access to the service via mobile. And, equally importantly, not every user only accesses YouTube on their Android or iOS device either. Sometimes, the web service is still needed. For those reasons, we’re starting this guide with a rundown of how to enable dark mode for YouTube on the web. And that’s a fairly easy process too if you know where to look.

To change back to a different theme
Now, going back to the Light theme is easy but how you do that will depend on how you’ve set the dark theme. If, for example, you’ve set the entire system theme to dark and want to keep it that way, you’ll need to follow the appropriate steps above to get to the theme selection setting. Then you’ll need to switch manually to the “Light theme” option. Conversely, if you want to change your system theme to light and already have that set to follow the system setting, simply change that setting to a light theme and YouTube will follow suit.
