Summary:The Landau Fermi-liquid theory is generalized for a system of fermions with a “color degree of freedom” (quark plasma). It is shown that the phase transition to color ordering state may occur depending on the change in thermodynamic parameters similar to a magnetic phase transition taking place for fermions with spin. The problem of thermodynamic stability of color and magnetic ordered Fermi-liquids is considered. It is shown that the stable color-ordered state of the plasma light quarks (u, d quarks) can be at the density n∼10 37 cm −3 and the temperature T∼100 MeV.
