Abstract: Spray color dispensing devices and associated systems and methods are disclosed. Color dispensing devices in accordance with certain embodiments include colorant contained in a pressure vessel, a pressure vessel holder including an attachment mechanism and an actuator system, and a control cable leading to a remote trigger controller. The remote trigger controller may be thumb operated or have a push button design, both of which may include a trigger locking device. There may be a deflector near the spray nozzle. The holder and actuator may allow only specifically designed pressure vessels. Also the pressure vessel may be insulated and/or heated to allow the color dispensing device to be used in cold environments.
