A modular color changer provides selected paint colors for spraying and recirculates nonselected colors. A module is provided for each paint color to be selected, and each module has an inlet for connection with a respective supply of paint, a recirculate outlet, a delivery outlet and a single valve member. The valve member may be selectively engaged with either a first or a second seat, depending upon whether paint at the inlet is to be directed to the recirculate outlet for return to the supply or to the delivery outlet for flow to a paint applicator. Solvent and air purge valves are upstream of the modules for cleaning the color changer of one color of paint in preparation for supplying another.
