So I've been trying to figure this out, and I've come to 2 possible conclusions, either QCD is broken, or it behaves completely different, with different characteristics than I am used to (such as possibly not obeying superposition?) If blue is attracted to both red and green, then shouldn't a blue quark see a "color neutral" object as having 2 attractive forces and 1 repulsive? Also, as I understand it, quark confinement is a consequence of the coupling constant being a function of r, as opposed to 1/r, like the other forces. So if you superimpose the fields from each quark, a blue quark, I would think would see a large attractive force, as there is 2*(growth factor associated with distance) as strong of a force acting on the blue quark attracting it as there is repelling it (from the other blue quark in the white object). Thanks for the indulgences.
