# AVVideoColorPropertiesKey

The key for a dictionary that contains properties specifying video color.

```
let AVVideoColorPropertiesKey: String
```

## Discussion

The dictionary must contain the keys [`AVVideoColorPrimariesKey`](/documentation/AVFoundation/AVVideoColorPrimariesKey), [`AVVideoTransferFunctionKey`](/documentation/AVFoundation/AVVideoTransferFunctionKey), and [`AVVideoYCbCrMatrixKey`](/documentation/AVFoundation/AVVideoYCbCrMatrixKey).
