Google Chrome Dark Mode on Windows
Google is working on integrating Dark Mode into the Google Chrome web browser on Windows. Google engineers started work on a dark theme for Chrome in 2018 and enabled it for Chrome on Mac OS X 10.14 and higher as a way for Mac users to use the system's Dark Mode feature in the browser.
It took Google a bit longer to integrate dark mode functionality in Chrome for the Windows operating system. The still-ongoing project is currently available as a preview for Chrome Canary only; Google plans to launch dark mode for Windows eventually.
Google Chrome will support the dark mode on all supported versions of Windows and not just Windows 10. Windows 10 has a dark mode feature that is very similar to that of Apple's Mac operating system.
Chrome's implementation will work that way on Windows 10 as well; it is unclear how it will work on older versions of the Windows operating system. One solution could be to implement a preference toggle or integrate dark mode as a theme that users can select.
Dark Mode is only available in Chrome Canary at the time of writing. Users may enable it by launching the Chrome web browser with a startup flag.
The interface looks like this when done.
Note that the implementation is not complete at the time of writing. The menu, for instance, uses black text on a dark background, and that makes text barely decipherable. The same is true for the right-click context menu. Many internal pages, e.g. chrome://extensions/, are not painted in darker colors either at this point in development.
Chrome Canary needs to be launched with the --force-dark-mode parameter. Right-click on the Chrome icon on the Windows taskbar and select Properties from the context menu (on some systems, you need to right-click again on Chrome Canary in that first menu, and then on Properties).
Add --force-dark-mode to the end of the Target field and make sure that there is a space between the command and the path, e.g. "C:\Users\Martin\AppData\Local\Google\Chrome SxS\Application\chrome.exe" --force-dark-mode.
Restart Chrome and it should launch with the dark theme enabled. Remove the parameter again to restore the light theme.
