# conversionBlackPointCompensation

An option for whether to apply black point compensation when converting between color profiles.

## Declaration

```swift
class let conversionBlackPointCompensation: CFString
```

## Discussion

Discussion ICC profiles specify how to convert the lightest level of white between color spaces, but they do not specify how black should be converted. To account for this, set a value of true for this key when creating a color conversion with the CGColorConversionInfoCreateFromList function.
