  We investigate the influence of charged kaon condensation in hadronic sector
on the formation of the electron-free charge neutral quark matter of
equipartition of three light flavors, i.e., a phenomenon called ``enforced
electrical neutrality" of the color-flavor locked (CFL) phase. We employ the
chiral quark model which is assumed to be applicable, "bottom-up," toward
chiral restoration while accessible to kaon condensation in the hadronic
sector. Approaching "bottom-up" the high density regime is more appropriate in
addressing the properties of compact stars than approaching "top-down" from
asymptotic QCD. It turns out that the presence of hadronic kaon condensation
makes the electron-free charge-neutral CFL phase energetically more favorable
with a relatively small color-superconducting gap $\Delta_0\sim 20$ MeV
compared to $\Delta_0\sim 70$ MeV required in the absence of such kaon
condensation.
