Although the human eye is quite capable of differentiating colors, different people will describe the same color differently. Consequently, a verbal description is inadequate in applications where precise color detection and management is required. A better solution describes the color in numeric terms using an adequately calibrated, color-sensing device. Such devices range from expensive laboratory-grade spectrophotometers to economical Red-Green-Blue (RGB) color sensors like those produced by Avago Technologies. Its’ wide range of color sensors are viable solutions for many of today’s practical color sensing and measuring applications.

The objective of this white paper is to provide insight into color perception, measurement and specification, and the application of data produced by color sensors. It will also provide a detailed look at Avago Technologies’ line of RGB color sensors and offer information on how these products may be utilized in various color-sensing applications.
