# vibrantDark

A dark vibrant appearance, available only in visual effect views.

```
static let vibrantDark: NSAppearance.Name
```

## Discussion

Vibrant appearances use color blending to make the foreground appearance stand out from the background more prominently.

Don’t assign an [`NSAppearance`](/documentation/AppKit/NSAppearance) object with this type directly to one of your views. Instead, assign a dark appearance to your view, make sure its [`allowsVibrancy`](/documentation/AppKit/NSView/allowsVibrancy) property is set to <doc://com.apple.documentation/documentation/Swift/true>, and embed the view in a visual effect view. When you do, AppKit updates your view’s appearance to this type.
