Adafruit TCS3430 / TCS34303 Ambient Tri-Stimulus Color Sensor

The Adafruit TCS3430 / TCS34303 (both names are used) Ambient Light Tri-Stimulus Color Sensor is a modern take on the common RGB color sensor: this time with CIE XYZ plus IR diode sensors rather than RGB, so you can match it to your existing color space.
