  We describe a realistic mechanism whereby black holes with significant QCD
color charge could have formed during the early universe. Primordial black
holes (PBHs) could make up a significant fraction of the dark matter if they
formed well before the QCD confinement transition. Such PBHs would form by
absorbing unconfined quarks and gluons, and hence could acquire a net color
charge. We estimate the number of PBHs per Hubble volume with near-extremal
color charge for various scenarios, and discuss possible phenomenological
implications.
