Switch to your Calendar, click the View tab on the top ribbon, select View Settings, and click Reset Current View to restore the default color mapping.
Open the Windows Control Panel, go to Programs and Features, right-click Microsoft 365, select Change, and choose Quick Repair.

Frequently Asked Questions
Why did my Microsoft 365 calendar colors suddenly change?
This usually happens due to a recent automatic update applied by Microsoft. In web versions, design tweaks (like switching to pastel shades) are deployed globally. In desktop versions, it might be a glitch in the application's current view settings.
Can I revert to the original darker category colors?
If you are on the desktop application, resetting your calendar view or changing the Office Theme often restores them. If you are using the online web version, this is likely a permanent design change by Microsoft, and your best option is to submit feedback.
Why can't I find the 'Reset View' option?
The 'Reset View' and 'Change View' options are exclusive to the Microsoft 365 installed desktop application. If you access your calendar through a web browser, these specific configuration menus will not be available.
