-The following table shows the color palette used by the Red theme.
+Besides the theme store schema, we also offer a simplified format for creating themes.
+SharePoint Framework provides ten built‑in themes—eight for light backgrounds, and two for dark backgrounds. If you want to build a custom theme, a good starting point is to pick one of these built‑in themes and adjust the values as needed. You can then use the [Add‑SPOTheme](/powershell/module/microsoft.online.sharepoint.powershell/add-spotheme) PowerShell cmdlet to create your custom theme with this simplified structure.

 * Control over which themes are available for use on pages within your sites. For example, you can define custom themes based on your organization's branding or identity, and make those the only available themes within your sites.
+* Support for up to 16 accent‑and‑background color pairs per theme, enabling multiple brand colors that reflect your organization’s identity.
