The Color 10 Click Board™ is carrying a VEML3328 sensor for RGB and IR light-sensing as well as the RGB diode incorporated on the board which makes it a good colour detection device when it's combined with a white LED. The VEML3328 sensor senses red, green, blue, clear and IR light by incorporating photodiodes, amplifiers, and analogue/digital circuits into a single CMOS chip.
With this sensor, the brightness and colour temperature of a display backlight can be adjusted based on the ambient light source, and it can differentiate indoor from outdoor lighting environments.
