The alternative [SU(3)]4 model of leptonic color and dark matter is discussed. It unifies at MU∼1014 GeV and has the low-energy subgroup SU(3)q×SU(2)l×SU(2)L×SU(2)R×U(1)X with (u,h)R instead of (u,d)R as doublets under SU(2)R. It has the built-in global U(1) dark symmetry which is generalized B–L. In analogy to SU(3)q quark triplets, it has SU(2)l hemion doublets which have half-integral charges and are confined by SU(2)l gauge bosons (stickons). In analogy to quarkonia, their vector bound states (hemionia) are uniquely suited for exploration at a future e−e+ collider.
