A signal generator for a color television transmitting system improves the picture quality when color encoded signals are reproduced in the picture displayed by a conventional color television receiver. The system utilizes a primary color level detector, a color-difference level detector, and a luminance signal producer which outputs a luminance signal in response to the difference between the primary color level signal output from the primary color level detector and a color-difference level signal output from the color-difference level detector. The output luminance signal is then utilized in the transmission of a color television signal so that a conventional color television receiver may display a color picture having an improved quality.
