# extendedLinearITUR_2020

The recommendation of the International Telecommunication Union (ITU) Radiocommunication sector for the BT.2020 color space, with a linear transfer function and extended range values.

```
class let extendedLinearITUR_2020: CFString
```

## Discussion

This color space has the same colorimetry as [`itur_2020`](/documentation/CoreGraphics/CGColorSpace/itur_2020), but uses a linear transfer function. You may encode component values below `0.0` and above `1.0`.
