Roblox is constantly adding new features to its platform to accommodate user preferences. Perhaps one of the most widely supported features for online applications these days is dark mode. Darker themes are often less harsh on a user's eyeballs, so having this option inside Roblox is nice to have for many people.
Switching to a Dark theme changes the default color scheme of the application, resulting in a black background, dark gray menus, and white text.
How to Activate Dark Mode in Roblox
To switch to a Dark theme in Roblox:
Log in to Roblox.com with your username and password.
Navigate to the Settings page and head into Account Info.
Look for the Theme option under the Personal section.
Click the Light dropdown and change it to Dark.

After switching to the Dark theme, you should see the color scheme of Roblox change. Many users find this more comfortable on the eyes, especially when using a large monitor in low light settings. This setting may not be optimal for everyone, so make sure to test it out and see if you prefer Roblox's Light or Dark theme better for yourself.
