# extendedSRGB

A color space object that represents an extended sRGB color space.

```
class var extendedSRGB: NSColorSpace { get }
```

## Return Value

The `NSColorSpace` object. This color-additive color space has red, green, blue, and alpha components.

## Discussion

This color space has the same colorimetry as sRGB, but component values below `0.0` and above `1.0` may be encoded in this color space. Negative values are encoded as the signed reflection of the original encoding function. `y(x) = sign(x)*f(abs(x))`
