    We describe a novel variation of the mirror twin Higgs model in which the color gauge group in both sectors is extended to SU(4)cand spontaneously broken to SU(3)cexclusively in the visible sector. Through this process, the mirrorZ2symmetry is spontaneously broken, allowing for a phenomenologically viable electroweak vacuum alignment. This structure produces interesting collider signatures, including heavy vectors and fermions with fractional electric charges. The twin sector, with unbroken SU(4)c, produces interesting cosmological characteristics, such as the possibility to reduce ∆Neffand stable spin-0 baryons. The enlarged top quark sector required by the extended color gauge symmetry preserves naturalness, with even less tuning than the original twin Higgs in many circumstances.
