# workingColorSpace

The working color space of the Core Image context.

## Declaration

```swift
var workingColorSpace: CGColorSpace? { get }
```

## Discussion

Discussion The working color space determines the color space used when executing filter kernels; Core Image automatically converts to and from the source and destination color spaces of input images and output contexts. You specify a working color space using the workingColorSpace key in the options dictionary when creating a Core Image context.
