Abstract: (Springer)

We present general formulae to compute Wilson line correlators with the Color Glass Condensate described by the McLerran-Venugopalan model. We explicitly construct a complete and non-orthogonal set of color-singlet bases and write matrix elements down, so that the exponential of the matrix leads to the Wilson line correlators. We further develop a systematic perturbative expansion of dipole Wilson line correlators in terms of 1/N

_{c}

where N

_{c}

is the color number. As a phenomenological application we calculate the flow harmonics v

_{n}

{m} in the dipole model and discuss the N

_{c}

scaling.
