An apparatus and a method are provided for continuously pumping liquid coloring composition to a destination without interruption in flow. This allows all loads delivered to multiple mixing chambers, for concrete, cement or the like, to be uniform, such that the resultant colors of the poured materials are uniform in color when compared to each other. The apparatus also includes a system for recirculating liquid coloring composition so as to reduce its viscosity such that it is of lower viscosity and therefore, flowable for pumping to the desired destination.
