Microsoft is set to introduce an updated default theme for its Office suite, which will be available to all Microsoft 365 subscribers next month, The Verge reports. The update includes the introduction of the Aptos font, which will be the new default font for programs such as Word, Outlook, PowerPoint, and Excel. This change marks the end of the default use of the Calibri font in Office, which has been in use for more than a decade and a half.

In addition to the font update, Microsoft is also making significant changes to the style and color palette used in Office documents by default. One of the most notable changes to the color palette is the removal of yellow, which will be replaced with a dark green hue. In addition, the light blue tone will be replaced with a richer darker turquoise to enhance the contrast between different shapes and lines in Office documents.

The changes are not limited to aesthetics. The default style in programs like Word and Outlook will be updated to improve readability, give a more professional look, and improve navigation. Jess Kwok, Microsoft 365 product manager, emphasized the changes, saying the goal is to make documents “easier to read, more professional looking, and easier to navigate.”

In July, Microsoft began testing these updates for its Microsoft 365 insiders. After successful testing, the company confirmed that these changes will be available to all users in September.
