We discuss the quantum state structure using the standard model for three colored quarks in the fundamental representations of SU(3) c making up the singlet ground state of the hadrons. This allows us to calculate a finite von Neumann entropy from the quantum reduced density matrix, which we explicitly evaluate for the quarks in a model for the meson and baryon states.
