+  AS7263 color sensor
+
+  Reads light readings and temperature readings from AMS AS7263 sensor.
+  Uses Sparkfun's AS726x library. Works with both Sparkfun and Adafruit 
+  breakout boards.
+
+  Datasheet: https://ams.com/documents/20143/36005/AS7263_DS000476_1-00.pdf/4bd22964-7fe0-2053-3e97-906f0836182f
+   
+   Near IR wavelengths:
+   610nm: R
+   680nm: S
+   730nm: T
+   760nm: U
+   810nm: V
+   860nm: W
+
+   According to the datasheet, all channels tested under 5700K White LED light.
+
+   based on Sparkfun libraries
