The van der Waals force induced by color-dependent confining potentials in nonrelativistic quark models of the [ital NN] interaction is investigated through a full resonating group calculation where the [ital NN] channel is coupled to a channel of two orbitally polarized color octets. While exchange terms can be neglected at low energies, they prove to be essential at higher energies, where the short and intermediate ranges of the induced interaction are probed. The extent to which the latter can be simulated by effective local potentials is examined. Finally, the van der Waals force induced by a strong enough confining potential is shown to give rise to unphysical bound states.
