We examine baryonic matter at a quark chemical potential of the order of the confinement scale mu(q) similar to Lambda(QCD). In this regime, quarks are supposed to be confined but baryons are close to the tightly packed limit where they nearly overlap in configuration space. We show that this system will exhibit a percolation phase transition when varied in the number of colors N-c: at high N-c, large distance correlations at the quark level are possible even if the quarks are essentially confined. At low N-c, this does not happen. We discuss the relevance of this for dense nuclear matter, and argue that our results suggest a new phase transition, varying N-c at constant mu(q).
