# saturation

An adjustment factor to apply to the overall color saturation of the rendered scene.

```
var saturation: CGFloat { get set }
```

## Discussion

A value of `1.0` (the default) leaves scene colors unchanged. Greater values result in oversaturated colors, and a value of `0.0` makes the rendered scene entirely grayscale.

To enable this behavior, you must first enable the [`wantsHDR`](/documentation/SceneKit/SCNCamera/wantsHDR) setting.
