Starting from a classical kinetic description of the quark-gluon plasma, we derive in the linear response approximation the color response function near thermodynamic equilibrium. From its poles the dispersion relations for the collective color modes (one longitudinal and one transverse) are obtained. The absence of Landau damping in the quark-gluon plasma is shown, and other damping mechanisms are discussed. A common misunderstanding concerning Landau damping in an electron plasma at low momenta is clarified. Finally we find the color correlation function in an equilibrium QCD plasma, using the fluctuation-dissipation theorem. Its relation to the gluon polarization operator in finite temperature QCD is discussed. The coefficient for color transport (color conductivity) is determined within a relaxation time model. Possible applications in the computation of plasma observables are pointed out.
