Color Aid takes its title from the brand name for packs of colored paper used in art making and teaching. The colors are stacked randomly and shot in close-up; each one acts as a color field which registers shifts in the grain of the paper and of the film. Each remains on screen from three to thirty seconds as Serra’s fingers enter the frame to wipe one off, revealing the next. Within the randomness of the wipes there are occasional abrupt changes of saturation pervading the frame. The soundtrack is of the sheets of paper being removed one after the other.
