An apparatus includes a selectively actuated fluid system having a plurality of selected fluid reservoirs, for example replaceable cartridge-type fluid reservoirs. A first subset of the reservoirs can be selectively actuated to dispense an individual fluid from the selected reservoir. A second subset of the reservoirs can be simultaneously actuated to dispense two or more fluids in mixed form.
