These are masses photons of the proton, but they have charge (red, green, blue) and are prisoner. So going back and carefully reading the Wikipedia article that you will here, I have removed some errors in my thinking. I now know that gluons do not stick, the nucleus together that is the job of mesons. Gluon have the same colour as quarks by are unrelated to them, they are only the colour vibration inside the strong force. I now have to study gauge symmetry.
