Color superconductivity of QCD at finite density, temperature and flavor asymmetry is studied within an approximation where the interaction is modeled upon four-fermion interactions. We calculate the thermodynamic potential in the so-called NJL-type model and study the phase structure at finite density, temperature and flavor asymmetry. We find that a mixed phase appears at sufficiently large flavor asymmetry and low temperature. A tricritical point in the T–μ B –μ I plane is also found.
