Vector mesons in three-flavor quark matter are studied on the basis of the in-medium QCD sum rules. We derive formulas relating the masses of vector mesons to chiral and diquark condensates at low, intermediate and high density regions. Due to the mass splitting caused by the diquark condensate, the singlet vector meson disappears from the low-energy spectrum, while the octet vector mesons survive as light excitations with a mass comparable to the fermion gap, which is closely connected to the light gluonic modes at high density.
