  We investigate the effects of the dynamical formation of the chiral
condensates on color superconducting phases under the electric and color
neutrality constraints at vanishing temperature. We shall show that the phase
appearing next to the color-flavor-locked (CFL) phase down in density depends
on the strength of the diquark coupling. In particular, the gapless CFL (gCFL)
phase is realized only in a weak coupling regime. We give a qualitative
argument on why the gCFL phase in the weak coupling region is replaced by some
other phases in the strong coupling, once the competition between dynamical
chiral symmetry breaking and the Cooper pair formation is taken into account.
