Values.GetAccountCustomizationsInputSourceReturns the current account customization settings, including account color, visible services, and visible Regions. Settings that you have not configured return their default values: visible Regions and visible services return `null`, and account color returns `none`. The visibleServices and visibleRegions settings control only the appearance of services and Regions in the Amazon Web Services Management Console. They do not restrict access through the CLI, SDKs, or other APIs.
