Virtual particles are created with a lifespan dependant on their mass. The field is filled with uncertainty. Randomness is the rule, but you can break the symmetry, and introduce order. Attraction or repulsion, creates convergence or divergence. The color represents the mass of the particle, after a while color convergence happens naturally.

The structure formed with the attraction force is not stable, because particles keep dying, and the system keeps “forgetting” the order created. If we don’t add a driving force, the system falls back into maximum entropy…
