> Since the parameter configuration of `Dual Color Streams` mode is quite different from that of `Default` mode, we provide the corresponding YAML configuration file.
Please set `config_file_path` to `gemini305_dual_color.yaml`, the configuration file is located in the config directory.
### Dual Color Mode
The `Dual Color Streams` mode supports left and right color streams at the same time. It does not provide depth or IR information, and the left and right outputs have consistent effects.
Because this mode uses a parameter configuration that differs significantly from `Default`, start it with the corresponding YAML configuration file:
```bash
ros2 launch orbbec_camera gemini_301_series.launch.py config_file_path:=gemini305_dual_color.yaml
```
The configuration file is located at `orbbec_camera/config/gemini305_dual_color.yaml`. It enables the `left_color` and `right_color` streams; other parameters inherit the defaults from `gemini_301_series.launch.py`.
The Gemini 301 series also supports Color preset selection with the `color_preset` parameter. Set the preset by name, for example `Default`, `Warm Biased AWB`, or `Cold Biased AWB`. The available names are reported by the device.
