Back in the olden days of computing, wage slaves sat in front of terminals with black backgrounds and lurid green text writing. The advent of the graphical user interface relieved this tyranny with a paper-white background from a bitmapped screen to write your WYSIWYG text, to showcase colourful graphics (and Fonts!).
Fast forward 30+ years and it seems every app and OS is running away from black text / white backgrounds, and heading for monochrome graphics and oppressive white text on a black background again.
Using Dark Mode, either in apps or in the operating system on your computer or phone, promises a variety of benefits – less noticeable flickering, reducing eye strain, avoiding bright lights in a dark environment, perhaps better readability and therefore productivity, and even lower energy costs.
Dark Mode has existed in Windows for a while – but ultimately, apps need to support the theme, too, and more and more are doing so – like new Edge browser, or Office apps (where you can set the Office Theme).
The announcement on Microsoft 365 functionality adds for August 2019 highlighted additional Dark Mode support coming to Outlook mobile apps and Outlook.com, saying, “Dark Mode is not only easier on the eyes and may extend battery life, it also enables you to comfortably continue using your device in places where the default bright mode isn’t appropriate, like darkened airplanes and movie theaters.”
So kids, next time you want to go and watch a movie & catch up on your email, make sure you’ve Dark Mode on!
