# hueComponent

The hue component value of the color.

```
var hueComponent: CGFloat { get }
```

## Discussion

Access this property only for colors in the [`calibratedRGB`](/documentation/AppKit/NSColorSpaceName/calibratedRGB) or [`deviceRGB`](/documentation/AppKit/NSColorSpaceName/deviceRGB) color spaces. RGB values are converted to HSB values as needed. Accessing it for other color types raises an exception.
