Preview a theme by selecting the thumbnail, then select Add to Chrome when you find one you like. Chrome will install the theme automatically, and your prior theme will be removed.
How to Remove Themes in Chrome
You can uninstall a theme from Chrome if you no longer wish to use it and want to go back to the default:
Select the three dots button in the top-right corner of Chrome and choose Settings from the drop-down menu. Select Reset to Default under Appearance. The classic Google Chrome theme will be restored.
Changing Chrome’s Color Scheme
The themes control Chrome’s appearance. You cannot independently modify colors apart from a theme package. The only way to change Google Chrome’s background colors is to change the theme.
Some operating systems override Chrome’s behavior, setting specific colors for various user-interface elements. For example, Windows supports an accent color, and different Linux desktop managers customize every element of a typical window.
How to Change Themes in the Chrome Mobile App
The mobile version of Chrome doesn’t have as many options as the desktop version, but you can switch between light and dark themes. Chrome will automatically switch to the dark theme when you turn on Android Dark mode or dark mode for iPhones and iPads.
