# accessibilityHighContrastVibrantDark

A high-contrast version of the dark vibrant appearance.

## Declaration

```swift
static let accessibilityHighContrastVibrantDark: NSAppearance.Name
```

## Discussion

Discussion Don’t assign an NSAppearance object with this type directly to one of your views. Instead, assign a dark appearance to your view. AppKit then returns this type when the user enables the Increase Contrast option in the Accessibility system preferences and the view’s allowsVibrancy property is true.
