An apparatus and method for supplying multi-color powder paint material to an applicator in which at least one canister is used. This invention can be utilized with multiple or with a single color of powder paint material. The preferred system includes two canisters that alternate in supplying powder to the applicator. While one canister supplies powder to the applicator, the other canister is purged of the previous material and filled with the next material to be sprayed. The canister has an interior sized to store a predetermined quantity of powder material. During operation, a powder transfer pump and a color changer transfer powder material from a storage container/hopper to the canister interior. A venturi pump then supplies the applicator with powder. After the object is painted, purge air is opened and the canister is purged of the previous material. The canister is then ready to start another cycle.
