The do-it-yourselfer plucked a gallon can of base paint from the shelf of the local hardware store
and handed it to Keith, the cheerful clerk at the paint counter. Their eyes met briefly and the
do-it-yourselfer silently handed over sample 150C-1, Musical Mist, to the clerk. It was
impractical to keep several gallons of every possible color on the shelves at the hardware store,
so the paint manufacturer had created clever workaround. The workaround was acomputer-
based system that added predetermined quantities of pigments to a gallon can of base paint
depending on the desired shade, in this case, Musical Mist. The hardware store now needed to
stock only the base paint, this machine, and a small supply of paint pigments in order to create
the thousands of colors in its catalog.
