Microsoft dark themes for SharePoint sites [MC1187401]

[Introduction]

Coming soon to SharePoint: Site owners and admins will be able to apply two new Microsoft-designed multi-color dark themes. These official themes offer modern dark color palettes with multiple colors combinations, enabling richer visual experiences and consistent branding across sites. Both themes are available out-of-the-box and can be configured via site settings.

This message is associated with Roadmap ID 526788.

[When this will happen:]

• Targeted Release (Worldwide): Rollout begins mid-December 2025, completes early January 2026
• General Availability (Worldwide, GCC, GCC High, DoD): Rollout begins mid-January 2026, completes early February 2026

[How this affects your organization:]

• Who is affected: SharePoint Site owners and SharePoint admins across all Microsoft 365 environments (Worldwide, GCC, GCC High, DoD)
• What will happen:
  • Two new Microsoft-designed dark themes (Dark Teal, Dark Blue) will be available out-of-the-box
  • Themes can be applied via “Change the look” in site settings
  • The themes update site headers, footers, section design, Text web part, and Design Ideas
  • Designed for low-light environments and compliant with Microsoft accessibility standards
  • No impact to existing themes or site functionality

Note: Previously applied PowerShell settings that disable all out-of-box themes from Microsoft remain effective, and the PowerShell command can still be used to manage the Microsoft theme availability.

[What you can do to prepare:]

• No admin action is required prior to rollout. After rollout:
• Notify site owners and users about the new dark themes
