# accessibilityDisplayShouldDifferentiateWithoutColor

A Boolean value that indicates whether the app avoids conveying information through color alone.

```
var accessibilityDisplayShouldDifferentiateWithoutColor: Bool { get }
```

## Discussion

If this property is <doc://com.apple.documentation/documentation/Swift/true>, the user interface avoids conveying information using color alone. Instead, use shapes or glyphs to convey important information.

Users can change this setting by choosing System Preferences > Accessibility > Display and selecting the “Differentiate without color” option. To receive updates when this setting changes, register for the [`accessibilityDisplayOptionsDidChangeNotification`](/documentation/AppKit/NSWorkspace/accessibilityDisplayOptionsDidChangeNotification) notification using [`notificationCenter`](/documentation/AppKit/NSWorkspace/notificationCenter).
