As a result of technological progress, video pictures have developed from monochrome to color. Thus, unique color techniques have opened new vistas in the art of producing images. The motion picture theory concerning color images, however, it still confined to the special, limited genre, reflecting the days when video pictures were predominantly black and white. In recent years, however, considerable progress has been made of coloration techniques in television and various other image media. Color images have penetrated so deeply into our daily life that the present period could well be described as the "color age." In these circumstances, it is of no small significance that efforts are being made to shed new light on the problem of color and image. In the production of monochrome images, its artistic value is found in the process of reducing natural colors to a gray-scale ranging from white to black. In other words, a sort of "abstraction" is made in such process. Unlike the the monochrome image, the color image has psychological and physiological problems regarding vision and perception unique to color. There can be no mere reproduction of natural color when it is made into images. Technological progress has improved coloration in various image media, including television. In order to develop the artistic character of color images, it is imperative to make wide use of the achievements in natural sciences, and to study these images from the standpoint of technical mechanism. A new theory of color images will be produced from such efforts.
