I want to use colour tracking with the webcam in my laptop to track the movement of a coloured ball on the end of my bow when I play so I can use it to change parameters, but try as I might, I can’t get my patch to do anything other than be a very small digital mirror…

you were not providing your min and max attributes properly.
the alpha value comes first for min and max (even though it’s last out of sukah).

make sure you have proper lighting and a very distinct color, and you should be good to go.
