Patrick, Sounds like you are making progress. That is good you have 3 colors. Not sure about the volume issue. That might be an independent issue with your settings.

i understand it better.ezbv4 sound panel is loud enough. but in script ,i put setvolume to 120 no effort. i need more light to in the room

Patrick, I would work on one issue at a time until you realize acceptable results. Concentrate on the multi-color object recognition until you are happy.
