The color signal reproducing apparatus of the invention is composed of multipliers (104, 105) for issuing X- and Y-axis signals by multiplying the color subcarrier signal of SECAM composite video signal by SIN component or COS component of local subcarrier signal, an ACC control voltage generator (106) for generating an ACC control signal by squaring and adding the X- and Y-axis signals in the burst gate pulse period, and a gain controller (102) for adjusting the amplitude of color subcarrier, and is constructed to control the gain controller by its ACC control signal. While using the color signal reproducing circuit commonly in three major television systems in the world, ACC of high precision is realized even in the case where the S/N state of SECAM color subcarrier signal is lowered.
