# didChangeNotification

Posted whenever a color list changes.

```
class let didChangeNotification: NSNotification.Name
```

## Discussion

The notification object is the [`NSColorList`](/documentation/AppKit/NSColorList) object that changed. This notification does not contain a `userInfo` dictionary.

To observe this notification using Swift concurrency, use [`NSColorList.DidChangeMessage`](/documentation/AppKit/NSColorList/DidChangeMessage).
