  Quark matter at sufficiently high density exhibits color superconductivity,
due to attractive gluonic interactions. At lower densities of order
$\Lambda_{QCD}^3$, it has been proposed that instanton generated vertices may
play an important role in the Cooper pair formation. We study the
renormalization group flow to the Fermi surface of the full set of couplings
generated by gluonic and instanton interactions. In earlier work we showed that
if the gluonic interactions dominate at the matching scale, their running
determines the scale of the Cooper pair formation Delta. Here we consider all
possibilities, including the one in which the instanton interactions dominate
all others at the matching scale. In the latter case we find that a number of
additional induced couplings (including the gluonic ones) reach their Landau
poles almost simultaneously with the instanton vertex. Presumably all
contribute to the Cooper pair formation. The most important consequence of
including all the couplings is a large increase in the gap size Delta.
