Color charge correlations in the proton at moderately small x are extracted from its light-cone wave function. The charge fluctuations are far from Gaussian. Correlators are described by n-body GPDs which exhibit interesting dependence on impact parameter as well as on the relative transverse momentum (or distance) of the gluon probes.

This analysis provides initial conditions for small-x Balitsky-Kovchegov evolution of the dipole scattering amplitude which include impact parameter and r*b dependence, and with non-zero C-odd component due to three-gluon exchange.

The color charge correlators could be measured through various exclusive processes at the EIC. They also determine unintegrated gluon distributions of the proton relevant for gamma - p, p - p, and p - A collisions..
