  The theory of ideal Yang-Mills fluids (IYMF; a Yang-Mills field coupled to a
fluid in the limit of infinite conductivity) is embedded in symmetric
hyperbolic form. This yields both causality and well-posedness of initial value
problems in this theory. The embedding is based on a covariant, constraint-free
divergence formulation of IYMF, developped by the author previously for
magneto-hydrodynamics. Expressions for the small amplitude wave structure are
also derived, showing that in general Alfven waves do not persist in the
presence of colored magnetic fields.
