# 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 | Required | When omitted | | --- | --- | --- | | `--background` | yes | | | `--editor-surface` | no | same as `--background` | | `--foreground` | yes | | | `--card` | no | same as `--background` | | `--card-foreground` | no | same as `--foreground` | | `--popover` | no | same as `--card` | | `--popover-foreground` | no | same as `--card-foreground` | | `--primary` | no | same as `--foreground` | | `--primary-foreground` | no | same as `--background` | | `--secondary` | no | same as `--muted` | | `--secondary-foreground` | no | same as `--foreground` | | `--muted` | no | same as `--secondary` | | `--muted-foreground` | no | `--foreground` mixed 70% into `--background` | | `--accent` | no | `--foreground` mixed 12% into `--background` | | `--accent-foreground` | no | same as `--foreground` | | `--border` | no | `--foreground` mixed 16% into `--background` | | `--input` | no | same as `--border` | | `--ring` | no | same as `--primary` | | `--chart-1` | no | same as `--primary` | | `--chart-2` | no | Orca's built-in color | | `--chart-3` | no | Orca's built-in color | | `--chart-4` | no | Orca's built-in color | | `--chart-5` | no | Orca's built-in color | | `--sidebar` | no | `--foreground` mixed 8% into `--background` | | `--sidebar-foreground` | no | same as `--foreground` | | `--sidebar-primary` | no | same as `--primary` | | `--sidebar-primary-foreground` | no | same as `--primary-foreground` | | `--sidebar-accent` | no | same as `--accent` | | `--sidebar-accent-foreground` | no | same as `--accent-foreground` | | `--sidebar-border` | no | same as `--border` | | `--sidebar-ring` | no | same as `--ring` | | `--worktree-sidebar` | no | same as `--sidebar` | | `--worktree-sidebar-foreground` | no | same as `--sidebar-foreground` | | `--worktree-sidebar-accent` | no | same as `--sidebar-accent` | | `--worktree-sidebar-accent-foreground` | no | same as `--sidebar-accent-foreground` | | `--worktree-sidebar-border` | no | same as `--sidebar-border` | | `--worktree-sidebar-ring` | no | same as `--sidebar-ring` |
