An apparatus ( 20 ) for recording a color image, comprises an image sensor ( 22 ) having a plurality of pixels ( 24 ) formed in a monolithic substrate. Each of the plurality of pixels ( 24 ) includes three floating gate semiconductor devices ( 80, 82, 84 ). A color tunable filter ( 30 ) is positioned between a photosensitive semiconductor device ( 86 ) and an electromagnetic radiation source. A FET transistor ( 130 ) has a drain ( 134 ) connected to the cathode ( 120 ) of the photodiode ( 86 ), and a source ( 136 ) connected to the anode ( 118 ) of the photodiode ( 86 ) and to control gates ( 94, 104, 114 ) of each of the three floating gate semiconductor devices ( 80, 82, 84 ). The color tunable filter ( 30 ) allows all desired combinations of colors to pass while each of the three floating gate semiconductor devices ( 80, 82, 84 ) are respectively selected to store the color image.
