We argue that a so far neglected dimensionless scale, the number of neighborsin a closely packed system, is relevant for the convergence of the large $N_c$expansion at high chemical potential. It is only when the number of colors islarge w.r.t. this new scale ($\sim \order{10}$) that a convergent large $N_c$limit is reached. This provides an explanation as to why the large $N_c$expansion, qualitatively successful in in vacuum QCD, fails to describe highbaryo-chemical potential systems, such as nuclear matter. It also means thatphenomenological claims about high density matter based on large $N_c$extrapolations should be treated with caution.

How large is "large $N_c$" for Nuclear matter?
