# accessibilityDisplayShouldReduceTransparency

A Boolean value that indicates whether the app avoids using semitransparent backgrounds.

```
var accessibilityDisplayShouldReduceTransparency: Bool { get }
```

## Discussion

If this property is <doc://com.apple.documentation/documentation/Swift/true>, don’t use semitransparent backgrounds in the user interface. For example, use only opaque windows.

Users can change this setting by choosing System Preferences > Accessibility > Display and selecting the “Reduce transparency” option. To receive updates when this setting changes, register to the [`accessibilityDisplayOptionsDidChangeNotification`](/documentation/AppKit/NSWorkspace/accessibilityDisplayOptionsDidChangeNotification) notification using [`notificationCenter`](/documentation/AppKit/NSWorkspace/notificationCenter).
