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.
