```cpp
class QRColor
```

**Namespace:** `datalogics_interface`

## Description

Used to control how the QR color is created.

**Note:** This class intentionally uses inline storage rather than the pimpl pattern because it is a trivial 3-member value type with no internal APDFL object to wrap.

**Referenced by:** [`QREncodeParams`](https://docs.datalogics.com/apdfl21/ModernCPP/21.4.0/class/QREncodeParams.md)
