Adafruit OPT4048 Tri-Stimulus XYZ Color and Lux Sensor

The Adafruit OPT4048 Tri-Stimulus XYZ Color, Light Temperature and Lux Sensor is a modern take on the common 'RGB' color sensor: this time with true "CIE" XYZ output so you can match it to your existing color space. It's also excellent for calculating color temperature, which is based on CIE, and as a bonus also has Lux calculation, up to 144 kLux for light measurement even in the brightest situations.
