Global Header Background Unavailable for SLDS 2 Themes

Why This Feature Was Removed

In some cases, global header background color selections made for SLDS 2 themes caused accessibility issues when dark mode was enabled. To ensure all users have an accessible experience, Salesforce removed this function from SLDS 2 custom themes. Salesforce is exploring ways to return this functionality in a way that maintains accessibility compliance.

Current Status

Dark mode is now available in beta for SLDS 2 themes in Starter orgs. Salesforce continues to evaluate how to restore global header background color customization while maintaining accessibility standards for dark mode users.

Alternatives While This Feature Is Unavailable

If you need to customize your org's header appearance, consider these alternatives:

1. Use available SLDS 2 Theme and Branding options: Button colors, page background colors, and brand colors are still configurable for SLDS 2 themes in Setup > Themes and Branding.
2. Use Classic themes: For orgs where global header background color is a requirement, Classic themes retain this configurability.
3. Experience Cloud Theme Editor: If you are using Experience Cloud sites, the Theme Editor provides more granular header control including background colors, independent of org-level SLDS 2 theme restrictions.
