PCT No. PCT/JP81/00229 Sec. 371 Date May 10, 1982 Sec. 102(e) Date May 10, 1982 PCT Filed Sep. 10, 1981 PCT Pub. No. WO82/01110 PCT Pub. Date Apr. 1, 1982.A color gain control circuit for use in a color television receiver set comprises manual and automatic gain controls which are connected in cascade fashion between a power source and a reference potential. The automatic gain control is positioned upstream of the manual gain control. By connecting the manual and automatic gain controls in cascade fashion as described above, these controls can be integrated together and the color gain control circuit can be simplified in its circuit construction, enabling the color amplification system to be integrated.
