# conversionBlackPointCompensation

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

```
class let conversionBlackPointCompensation: CFString
```

## 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 <doc://com.apple.documentation/documentation/Swift/true> for this key when creating a color conversion with the [`CGColorConversionInfoCreateFromList`](/documentation/CoreGraphics/CGColorConversionInfoCreateFromList) function.
