A two-flavor color-superconducting Nambu-Jona-Lasinio model is introduced at finite temperature T, chemical potential {mu}, and in the presence of a constant magnetic field e-tildeB. The effect of (T,{mu},e-tildeB) on the formation of chiral- and color-symmetry-breaking condensates is studied. The complete phase portrait of the model in T-{mu}, {mu}-e-tildeB, and T-e-tildeB phase spaces for various fixed e-tildeB, T, and {mu} is explored. A threshold magnetic field e-tildeB{sub t}{approx_equal}0.5 GeV{sup 2} is found, above which the dynamics of the system are solely dominated by the lowest Landau level, and the effects of T and {mu} are partly compensated by e-tildeB.
