A theory of modified quantum chromodynamics is presented in which color is realized as a global rather than local SU(3) symmetry. Quarks and gluons are then free to exist, but below a certain energy threshold they are still effectively confined by the same dynamics as in quantum chromodynamics. In addition to the massive vector-gluon octet, the theory also contains an octet and two singlets of Higgs particles, or scalar gluons. Asymptotic freedom is maintained by the imposition of eigenvalue conditions on all coupling constants such that only one of them, say the gauge coupling g, is an independent parameter. This is shown to imply the existence of extraordinary quarks which are not triplets under color SU(3).
