In this episode, Helge and Michael give an overview of color sensors. A color sensor separates light reflected from a sample into several portions of the visible spectrum and returns an intensity value for each of these sub-spectra. The distribution of these values reveals the spectral properties—and thus the color—of the target. --A color sensor can differentiate between multiple colors with high precision --Commonly referred to as a Color-Mark Sensor --A color sensor is capable of detecting very minute color variations
