Abstract: A method and apparatus for batch tinting paint by adding preselected amounts of selected paint colorants to a batch of base paint in a paint vessel at a mixing station. The different paint colorants are stored at a colorant storage station, and a charge of paint colorant consisting of preselected amounts of one or more selected paint colorants to be used in tinting a batch of base paint are delivered to the inlet end of a single tube delivery line extending from the storage station to the mixing station. The charge of paint colorant is thereafter purged from the line and delivered to the mixing vessel by passing a purging fluid including a purging liquid compatible with the colorant into the line while delivering the purging liquid and colorant to the mixing vessel.
