  The origin of the breaking of conventional linear k_\perp-factorization for
hard processes in a nuclear environment is by now well established. The
realization of the nonlinear nuclear k_\perp-factorization which emerges
instead was found to change from one jet observable to another. Here we
demonstrate how the pattern of nonlinear k_\perp-factorization, and especially
the role of diffractive interactions, in the production of dijets off nuclei
depends on the color properties of the underlying pQCD subprocess.
