ABSTRACT:
In a color television receiver, a color television picture on a screen is blanked at a predetermined area and a first reference color image, the hue of which is varied in response to a hue control of said color television picture, and a second reference color image, the hue of which is fixed, are displayed on the screen at said blanked predetermined area. Hue control is achieved by coinciding the hue of the first reference color image with the hue of the second reference color image by means of a manually adjustable hue control circuit.
