Precise measurements are vital to colour sensor sensitivity

Keywords:colour sensors  RGB  light-to-analogue 

Although the human eye is very capable of differentiating colours, people will describe the same colour differently. This makes verbal description inadequate in applications that require precise colour detection and management.

A better solution is to describe colour in numeric terms using adequately calibrated colour-sensing devices—from expensive laboratory—grade spectrophotometers to economical RGB colour sensors.

This article will provide some insight into colour perception, measurement and specification, and how the data produced by colour sensors is applied.
