Reset Custom Theme Colors in Microsoft 365 Admin Center
Resetting the organization's custom theme colors to default will restore the original dark appearance of the SharePoint interface.
Microsoft 365 allows administrators to customize the top navigation bar and theme for the entire organization. When these settings are unexpectedly altered or corrupted by an update, resetting the theme colors is the quickest way to restore the default interface.
Navigate to the Microsoft 365 admin center (admin.microsoft.com) and log in using your administrator credentials.
In the left-hand navigation menu, click on 'Settings', then select 'Org settings'.
Click on the 'Organization profile' tab located at the top of the settings page.
From the list of profile options, select 'Custom themes' to open the theme configuration panel.
Under the 'Default theme' section, select the 'Color' tab, and click the 'Reset Colors' button. Save your changes to restore the default dark theme.

Try WPS Office for a Lightweight and Customizable Experience
While Microsoft 365 offers comprehensive admin controls like custom SharePoint themes, managing cloud-based settings can sometimes be complex. If you just need powerful, reliable document creation tools without the heavy administrative overhead, WPS Office is an excellent free alternative that includes its own built-in Dark Mode.
- 1. Download and Install: Download the free WPS Office installer from the official website and complete the quick installation process.
- 2. Open Any Document: Launch WPS Office and open a Writer, Spreadsheet, or Presentation file.
- 3. Enable Dark Mode: Click the 'Eye Protection and Night Mode' switch located at the bottom status bar to instantly switch your workspace to Dark Mode.

Frequently Asked Questions
Why did my Microsoft 365 admin center theme change unexpectedly?
Theme changes can occur due to major Microsoft system updates, browser caching issues, or if another administrator accidentally modifies the organization profile settings.
Do I need global admin rights to change the Microsoft 365 theme?
Yes, you typically need Global Administrator credentials or a specialized admin role to access and modify the Org settings and Organization profile in the Microsoft 365 admin center.
Will resetting the custom theme affect my SharePoint site contents?
No. Resetting the custom theme in the Microsoft 365 admin center only affects the global navigation bar and administrative interface colors; it does not alter your actual SharePoint site content, data, or custom site templates.
Can individual users override the organization's custom theme?
While the admin center sets the default global theme for the organization, individual users can sometimes customize their own Microsoft 365 theme settings via their personal profile settings (the gear icon in the top right corner of the suite bar), which will override the admin default for their view.
