A cathode ray tube device for the presentation of color images, which is equipped, at least, with an electronic gun, which produces a number of electronic beams that scan by line a color selection electrode having orifices arranged in a systematized form, and which; you do percuten on points of the presentation screen, characterized in that the quotient of the distance between two successive lines of exploration on the screen and the distance between the projections on the screen of two successive holes in the color selection electrode covers so less two distances between two successive lines of exploration, which are different because of the different numbers of scan lines per image, between (see formula) and (see formula), where n is a natural number, and representing α the minimum angle between the direction perpendicular to the scanning lines and the direction of the distance on the screen between the projections of two successive holes of the color selection electrode.
