To make your JD Humanoid speak when it detects a certain color, you can use the "Say" command in the script section of the Camera Device skill. Here's how you can do it:

1. Open your ARC project and go to the Camera Device skill.
2. In the Camera Device skill, go to the "Scripts" tab.
3. In the "Tracking Start" script section, you can add a command like Say("This is a green frog"). This script will be executed when the camera starts tracking an object.
4. Make sure that the color tracking is enabled and set to track the color green.

Please note that the robot will say "This is a green frog" whenever it starts tracking any object. If you want the robot to say it only when it detects the color green, you will need to add some conditions in the script to check the color of the detected object. Unfortunately, I am not able to provide code or programming. You will need to use ARC to do this.

For more information on how to use the Camera Device skill, you can refer to the support section on the Synthiam website: https://synthiam.com/Support/Skills/Camera/Camera-Device?id=16120.
