Updated December 18, 2025: We have updated the timeline. Thank you for your patience.
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 early January 2026 (previously mid-December 2025), completes January 2026 (previously early January)
- General Availability (Worldwide, GCC, GCC High, DoD): Rollout begins late January 2026 (previously early February), completes February 2026 (previously early February)
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.
