This is an Arduino/Fishino RGB Color Sensor breakout uses TAOS TCS3200 RGB sensor chip and 4 white LEDs.
The TCS3200 color sensor can detect and measure a nearly limitless range of visible colors.
The TCS3200 has an array of photodetectors, each with either a red, green, or blue filter, or no filter (clear).
The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors.
Internal to the device is an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.

The Module is equipped with 4 white light LED.
When an object is placed in front of the module, at a distance of not more than 10 mm, this is illuminated by the 4 white LEDs and the reflected light will hit the 64 photodiodes, obtaining a square wave (duty cycle 50%) with a frequency directly proportional to the intensity of the reflected light.
