The string-flip model of quark confinement is extended and applied to two-baryon systems with color, spin, and flavor degrees of freedom. The model avoids a pathological color van der Waals force, unlike a conventional two-body quark-confining potential model. Resonating-group-method calculations of the N-N phase shifts are presented for several different color-dependent potentials. A realistic model with a short-range interquark potential and an effective meson-exchange interaction is proposed and found to reproduce ${}_{}{}^1{}_{}{}^{}\mathrm{S}_0^{}{}_{}{}^{}$ N-N scattering data very well.
