# extendedSRGB

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

## Declaration

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

## Return Value

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

## Discussion

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))
