Not everyone loves white text on a black background, but for those who do, this is for you. Some people find it easier to write on a black background in Microsoft word. You don’t have to alter the template to change the background — it’s much more simpler than that.
Simply switch to the X-ray mode, which changes your entire Mac screen into a glowing mixture of black-and-white color.
Not just Microsoft Office products but also your Mac applications, games, and everything else in between, will enjoy black background with a glint of X-ray silver lining on every Window.
Activate Black Background on Mac
To activate the X-ray mode, you can use this keyboard combo: Control + Option + Command + 8
Alternatively, you can go to System Preference -> Universal Access, and select the tab Seeing. There’s an option under the Display section to set White on black. You can use grayscale and set contrast to your needs.
