## Theme hot-reloading

OpenCode supports hot-reloading themes without restarting the application. This is useful for testing custom theme changes in real-time or integrating with dynamic theming tools.

To trigger a theme reload, send the `SIGUSR2` signal to the OpenCode process:

```bash no-frame
pkill -USR2 -x opencode
```

This will:
1. Clear the cached terminal color palette
2. Reload all custom themes from disk
3. Re-apply the current theme with updated colors

## Using a theme

You can select a theme by bringing up the theme select with the `/theme` command. Or you can specify it in your [config](/docs/config).
