A paint supply device includes a container defining a paint-storing chamber therein, a piston-and-cylinder assembly, and a finger-holding unit connected to the container. The container has a top threaded portion, and a cap secured to the top threaded portion. The piston-and-cylinder assembly includes a cylinder extending into the paint-storing chamber, and a hollow piston rod extending into the cylinder for withdrawing paint from the container to a paint applicator and having a top end disposed above the cap. A connecting head is connected to the top end of the piston rod, and is adapted to be connected to the paint applicator. The finger-holding unit has a hook member defining at least one finger-receiving recess disposed between the connecting head and the cap.
