  On the basis of the method of Cartan exterior forms and extended Lie
derivatives, a hydrodynamic equation of the Euler type that describes a perfect
spin fluid with an intrinsic color charge in an external non-Abelian color
field in Riemann-Cartan space is derived from the energy-momentum
quasiconservation law. This equation is used to obtain a self-consistent set of
equations of motion for a classical test particle with a spin and a color
charge in a color field combined with a gravitational field characterized by
curvature and torsion. The resulting equations generalize the Wong equation,
which describes the motion of a particle with an isospin, and the Tamm-Good and
Bargmann-Michel-Telegdi equations, which describe the evolution of a
charged-particle spin in an electromagnetic field.
