Now, when dark mode is turned on, some websites that normally would stay white will switch their colour scheme to dark as well. This feature can be tested on the Bing search or on a Wikipedia website.
Dark mode can be turned on in the Appearance settings section. The feature was spotted on the Canary build v95.0.997.0.
Lots of popular websites support this behaviour natively (like TestingCatalog) but Edge can now make sure that you will never be looking into an eye-blowing white projector in the middle of the night.
