Abstract
A color signal controlling apparatus for controlling a color signal in a color television receiver. The apparatus has a color signal modifier for modifying a color signal; and a color signal stabilizer supplied with a color signal from the color signal modifier for detecting a color reference signal in a vertical blanking period and for stabilizing the color signal with reference to the color reference signal. The apparatus further has a switching circuit for supplying a switching signal in the vertical blanking period to the color signal modifier. The switching signal prohibits the color signal modifier from modifying the color reference signal to keep the desired operation of the color signal stabilizer.
