Microsoft Office allows you to easily switch between dark, light, colorful, dark grey, and system themes. Switching between modes will change the appearance of the toolbar, ribbon, and document canvas. The selected theme will apply to all Office apps.
In the 'Office Theme' drop-down menu, select 'White' for Light Mode or 'Black' for Dark Mode. To change Microsoft Word to Light or Dark Mode, open Word and click 'File' > 'Account' or 'Options'.
