Nonequilibrium simulations of two-dimensional shear flow have shown that the viscosity is well defined in the large-system "hydrodynamic" limit. Those simulations, with up to a quarter million particles, were carried out at fixed energy and strain rate. Here we explore the mass current response to an external "color field" E for N particles, half with "color charge" + 1, and half with -1. The fixed-field large-N "color conductivity" K=( vIE), with the energy per particle held constant, likewise
