# Orca app theme tokens Every key an app theme may set in `tokens` (see [plugin themes](plugin-themes.md)). Any other key is refused. An omitted token falls back as listed; when that source is omitted too, it falls back the same way in turn. | Token | Paints | Required | When omitted | | --- | --- | --- | --- | | `--background` | App canvas | yes | | | `--editor-surface` | Code editor and notebook background | no | same as `--background` | | `--foreground` | Body text | yes | | | `--card` | Cards and panels | no | same as `--background` | | `--card-foreground` | Text on `--card` | no | same as `--foreground` | | `--popover` | Menus, popovers and dialogs | no | same as `--card` | | `--popover-foreground` | Text on `--popover` | no | same as `--card-foreground` | | `--primary` | Primary buttons | no | same as `--foreground` | | `--primary-foreground` | Text on `--primary` | no | same as `--background` | | `--secondary` | Secondary buttons | no | same as `--muted` | | `--secondary-foreground` | Text on `--secondary` | no | same as `--foreground` | | `--muted` | Quiet fills | no | same as `--secondary` | | `--muted-foreground` | Secondary text | no | `--foreground` mixed 70% into `--background` | | `--accent` | Hover and selected fills | no | `--foreground` mixed 12% into `--background` | | `--accent-foreground` | Text on `--accent` | no | same as `--foreground` | | `--border` | Borders and separators | no | `--foreground` mixed 16% into `--background` | | `--input` | Input borders | no | same as `--border` | | `--ring` | Focus rings | no | same as `--primary` | | `--chart-1` | Chart series 1 | no | same as `--primary` | | `--chart-2` | Chart series 2 | no | Orca's built-in color | | `--chart-3` | Chart series 3 | no | Orca's built-in color | | `--chart-4` | Chart series 4 | no | Orca's built-in color | | `--chart-5` | Chart series 5 | no | Orca's built-in color | | `--sidebar` | Right sidebar and settings navigation | no | `--foreground` mixed 8% into `--background` | | `--sidebar-foreground` | Text on `--sidebar` | no | same as `--foreground` | | `--sidebar-primary` | Primary controls in sidebars | no | same as `--primary` | | `--sidebar-primary-foreground` | Text on `--sidebar-primary` | no | same as `--primary-foreground` | | `--sidebar-accent` | Hover and selected rows in sidebars | no | same as `--accent` | | `--sidebar-accent-foreground` | Text on `--sidebar-accent` | no | same as `--accent-foreground` | | `--sidebar-border` | Sidebar borders | no | same as `--border` | | `--sidebar-ring` | Focus rings in sidebars | no | same as `--ring` | | `--worktree-sidebar` | Left workspace sidebar | no | same as `--sidebar` | | `--worktree-sidebar-foreground` | Text on `--worktree-sidebar` | no | same as `--sidebar-foreground` | | `--worktree-sidebar-accent` | Hover and multi-selected rows in the workspace sidebar | no | same as `--sidebar-accent` | | `--worktree-sidebar-accent-foreground` | Text on `--worktree-sidebar-accent` | no | same as `--sidebar-accent-foreground` | | `--worktree-sidebar-border` | Workspace sidebar borders | no | same as `--sidebar-border` | | `--worktree-sidebar-ring` | Focus rings in the workspace sidebar | no | same as `--sidebar-ring` | | `--worktree-sidebar-active` | The current workspace row;
