Abstract
A beam-indexing color television receiver having a phosphor screen including one index stripe for every predetermined integral number of phosphor stripe sets each including a red, a green and a blue phosphor stripe. The minimum bias current is supplied to the picture tube only upon detection of a chrominance signal within a predetermined hue range around a specific chrominance signal corresponding to the phosphor stripe which is in the middle between adjacent index stripes on the phosphor screen, thus attaining a superior color saturation and contrast.
