It is assumed that the psi(J) and psi' mesons at 3.1 and 3.7 GeV are color excitations, and that color symmetry is broken badly. A simple symmetry-breaking mechanism leads to the prediction of a total of nine vector and nine pseudoscalar mesons in the 3--4 GeV region. This is in striking contrast with the predictions of both the standard color-excitation model and the charm model of the psi(J) and psi'. An estimate is made of the mass of a predicted baryon-resonance multiplet. Several other predictions of the model are compared with those of the charm model and with experiment. (AIP)
