Using this extension you can customize many colors including background and link colors on the options page of the extension if you don't like the default configuration.

Features:
1. You can define a period for the extension to automatically activate the dark theme
2. You can append your custom CSS rules to the default dark theme from the options page
3. You can ask the extension to automatically follow the system color scheme (turn dark theme on when the preferred color scheme is dark and turn it off when not) (this feature uses the JavaScript's matchMedia method to install a listener for prefers-color-scheme).

Some of the Supported hostnames
1. Google Search (www.google.com)
2. Google Images (images.google.com)
3. SSL Google Search (encrypted.google.com)

The extension also supports localized Google domains like www.google.fr for the Fr version of Google Search.

Please make sure you don't have the Stylish extension with styles installed that might conflict with this add-on.
