Color concentrate compositions are disclosed, which contain colorant(s), binder, and polymer compatible with the base polymer to which the concentrate is intended to be added. The colorant is preferably one or more pigments. The compatible polymer preferably is the same polymer as the base polymer, although not necessarily the same molecular weight. The binder also serves as a surfactant to protect the compatible polymer. The presence of the compatible polymer in the concentrate enhances pellet integrity and adds the function of rheology modification to the base polymer when the concentrate is added.
