Colour enhancement. Remote-sensing systems that operate VIS-NIR [visible, near-infrared] range typically include three channels that approximate the response of the human eye, and afford the opportunity to construct RGB [red-green-blue] composite image that resembles natural colour. Unfortunately, when displayed, many such images appear to have mostly tones of gray … Contrast stretching may help, but the colours tend to be far less saturated than we are accustomed to when observing or photographing in the field. Besides trying standard stretches, [there is] another way to enhance natural colour … The results of enhancing images to bring out colour are highly dependent on the nature of landscape and the image measurements.
