How to change theme Color in MS. Word

 Posting on the Office Insider blog, Ali Foretell, Program Manager on the Word team working on Accessibility features, explains how a new option is being added for dark mode users. It's already possible to make the ribbon and toolbars dark, but the document remained bright white. A new feature allows the page to go dark, too, with the text adjusting accordingly to remain visible. Microsoft has announced that the dark mode offered for Word is being improved and allowing for an even darker experience.

To enable dark mode, navigate to File > Account > Office Theme > Black. You can also toggle between black and white page backgrounds by clicking View > Switch Modes. When the document canvas color is dark, the rest of the colors used for text and graphics will be altered automatically. As Foretell explains, "reds, blues, yellows, and other colors will be shifted slightly to mute the overall effect of the color palette and look more visually pleasing with the new dark background.
