+### 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.

+
+`Dual Color Streams` 模式支持左右彩色同时出流，无深度 IR 信息，左右路输出效果一致。
+
+由于该模式的参数配置与 `Default` 模式差异较大，请使用对应的 YAML 配置文件启动：

+配置文件位于 `orbbec_camera/config/gemini305_dual_color.yaml`，其中已启用 `left_color` 和 `right_color` 流；其他参数沿用 `gemini_301_series.launch.py` 的默认配置。
 
 Gemini 301 系列也支持通过 `color_preset` 参数选择彩色 preset。请按名称设置，例如 `Default`、`Warm Biased AWB`、`Cold Biased AWB`，可用名称以设备返回为准。
