Motivated by the observed ratio of dark matter to baryon mass densities, $\rho_D/\rho_B \simeq 5$, we propose a theory dark-color unification. In this theory, visible masses are fixed confinement scales, which determined be nearby in through unification and gauge theories at high scale. Together with mechanism for darko-baryo-genesis, arises naturally from grand sector, densities two sectors mu...
