# vImageCVImageFormat_SetColorSpace(_:_:)

Sets the color space of a Core Video image format.

```
func vImageCVImageFormat_SetColorSpace(_ format: vImageCVImageFormat, _ colorspace: CGColorSpace!) -> vImage_Error
```

## Parameters

`format`

The Core Video image format to update.

`colorspace`

The new color space for the format.

## Return Value

[`kvImageNoError`](/documentation/Accelerate/kvImageNoError); otherwise, one of the error codes in <doc://com.apple.documentation/documentation/Accelerate/data-types-and-constants>.

## Discussion

For RGB, indexed, and grayscale images, the color space of a Core Video image format describes the image encoding.

For YpCbCr images, the color space describes the image encoding of the RGB image that’s the result of unapplying the RGB-to-YpCbCr conversion matrix.
