1. A hardware system for providing a natural language objective assessment of relative color quality between a series of reference images from video images and a series of source images from video images, comprising: a processor including: a moving image color appearance model structured to determine a difference measurement between selected ones of the reference images and a corresponding source image of the series of source images; a color convertor structured to receive the difference measurement and to determine a color attribute change based on the difference measurement; a magnitude index facility structured to determine a magnitude of the determined attribute change; a natural language selector structured to generate a natural language report of the color attribute change and of the magnitude of the color attribute change; and an output module structured to communicate the natural language report to a user of the system.
