We all want Microsoft to bring some consistency to Windows theming and design language. But we're not gonna get it from Microsoft—instead, it's coming from Google. The latest Chrome Canary build allows you to match your browser theme to your Windows accent color. All you need to do is flip the new "follow device colors" toggle in the Customize Chrome panel. Presumably, this feature will trickle down to mainline Chrome builds within the next few months.
The new Chrome customization setting was discovered by Leo Varela, who shared screenshots on Twitter and Reddit. Technically speaking, Chrome has been able to match Windows theming for some time, though this functionality was previously limited to dark and light mode. (Note that the "follow device colors" toggle has no impact on dark and light mode settings. You can match your system's dark mode without matching the accent colors, and vice versa, if you wish.)
There's just one thing to consider: do people really need this feature? Most Windows users set an accent color and never change it — the new "follow device colors" toggle may save them about a minute of manual customization in Chrome. This feature may be useful to those who automatically shuffle their Windows theme, but to most people, it's just another setting that will eat up space on the Customize Chrome page.
For what it's worth, there are several Chrome themes on the Chrome Web Store. You aren't limited to using basic colors, and you can build your own Chrome theme (with background images and other cool stuff) if you're willing to put in some work.
To test Windows accent theming in Chrome, install the latest Chrome Canary build from Google's website (or update your installation if you already have Chrome Canary). You don't need to activate any flags or jump through any hoops. Simply go into Customize Chrome and toggle "follow device colors." Google regularly experiments with new features in Chrome Canary, and we assume that this particular feature will arrive in mainline Chrome releases within the next few months, though Google hasn't commented on the rollout. Also, we don't know if this feature will arrive on macOS, though it's the default behavior on Chrome OS.
