  We review, clarify, and extend the notion of color-flavor locking. We present
evidence that for three degenerate flavors the qualitative features of the
color-flavor locked state, reliably predicted for high density, match the
expected features of hadronic matter at low density. This provides, in
particular, a controlled, weak-coupling realization of confinement and chiral
symmetry breaking in this (slight) idealization of QCD.
