To align the Salesforce mobile app with a company's visual identity, a Platform Administrator can customize specific branding elements through the Salesforce Mobile App Customization settings. The two primary areas available for branding are:

Loading Page Logo:This allows the administrator to upload a company logo that appears when a user first opens the app.

Header Background Color: This allows the administrator to set the primary brand color for the top header area of the mobile interface.

These settings ensure that the user experience feels consistent with the company's internal branding from the moment they log in. Option A and B are incorrect because Salesforce does not currently allow for granular "App header" vs "Header background" color separation or the modification of the "Record background color," as the app maintains a standardized background for accessibility and readability. Customizing the loading screen and header is the standard way to implement a mobile rebrand.
