Chrome 73 has been officially released to all users today, and has brought several new enhancements, including the long-awaited dark mode for macOS. ("Windows support is on the way," read the release notes.)
Dark mode was first announced to Chrome last month, but today's version has made it official. It works the way you expected: if dark mode is enabled on your computer (check here for macOS and here for Windows 10), Chrome will automatically assign the appropriate theme to match, in what essentially resembles the darkest Incognito mode. browser. Menu bars (Incognito Mode while using dark mode in Chrome seems virtually identical, save a new icon in the menu bar).
It's not technically the first time that Chrome offers dark or themed options – Google has offered themes for Chrome (including the dark styles of esque mode) in the Chrome Web Store for a while, but Today's update makes it more official at the system level. So, instead of having to switch back and forth manually, Chrome will simply respect whatever its native configuration is.
Conversely, if you're not a fan of the new and dark colors of Chrome, you can use the Chome themes to change your color scheme to a lighter style, which seems to be the only way to change the color before to change color. your full operating system configuration will return to the light mode.
Correction, 7:16 PM ET: It seems that Windows is still not compatible, contrary to what we originally reported, it is Mac for now.
