Influences of nonlinear screening on effective interactions between spherical macroions in charged colloids are described via response theory. Nonlinear screening, in addition to generating effective many-body interactions, is shown to entail essential corrections to the pair potential and one-body volume energy. Numerical results demonstrate that nonlinear effects can substantially modify effective interactions and thermodynamics of aqueous, low-salt suspensions of highly-charged macroions.
