# saturation

A mode that uses the luminance and hue values of the background with the saturation of the source image.

## Declaration

```swift
static var saturation: GraphicsContext.BlendMode { get }
```

## Discussion

Discussion Areas of the background that have no saturation — namely, pure gray areas — don’t produce a change.
