A color sensor comprises a cell group comprised of a plurality of photovoltaic cells having a different photosensing wavelength area and being electrically, series-connected, a connection circuit electrically connected across both terminals of the cell group to provide an electrically closed circuit, and a sensing circuit adapted to sense a voltage across both terminals of the respective photovoltaic cell and to evaluate a color component of light incident on the color sensor.
