Yes, there is a dark mode for Chrome on Android devices. It was first rolled out for Chrome on desktop in April 2019, then expanded to Chrome on mobile devices such as Android and iOS.
To turn on dark mode on Chrome for Android, first launch the Chrome app on your device. Open the menu by tapping the three dots at the top right corner. Scroll down and select “Settings” > “Themes” > “Dark.” This will cause the webpages to render darker and use more contrasting colors, making the viewing experience more comfortable and easier on the eyes.
You can also enable dark mode on some websites. This can be done by clicking on the three dots at the top right corner when in the website, then selecting “Settings” > “Appearance” > “Dark Mode.”
