Default font change
Midway through the life cycle of Office 2021, after two years of evaluating five newly commissioned fonts in July – the default font across all Office applications was changed to Aptos. This marked the first time since 16 years that Microsoft had changed the default fonts.
User interface
The default interface, when the Office theme set to Use system setting, dark gray, black, or white, shows a Mica background (whence the name) across the top of each screen; the application icon is in the top left corner. When Colorful is selected (must be done manually), a band in the application color shows across the top of each screen; this is called the Metro background.
