The quark color magnetic moment is examined in the framework of the interaction of a quark with a constant external color magnetic field. Quark and gluon propagators in the external field are evaluated and shown to lead to a field-dependent anomalous magnetic moment ..mu..= (gh/2mc) (3..cap alpha../sub s//4..pi..) ln(gB/m/sup 2/), where B is the external field strength. Comparison is made with the behavior of the electron anomalous magnetic moment in strong fields. Possible phenomenological consequences for hadron mass splittings are discussed.
