If you’re experiencing font color issues in Microsoft Word 365 where changes to font size or font color aren’t applying correctly, the issue may not be within Word itself but rather a setting in Windows 11. A surprising yet effective fix is to reset your Windows 11 theme to a default one. This article will guide you through the troubleshooting process and provide a reliable solution.
