In a signal supplying circuit for a color picture tube, the luminance signal component of a color signal is divided into a high-frequency component and a low-frequency component, the low-frequency component is supplied to a demodulator for the chrominance signal component of the color signal so that the output of the demodulator which is supplied to the output amplifier contains the demodulated chrominance signal component mixed with the low-frequency luminance signal component, and the high-frequency luminance signal component is separately applied to an input of the amplifier for mixing in the output of the latter with the chrominance signal component and the low-frequency luminance signal component so as to constitute therewith a complete color video signal for application to a color picture tube.
