Vision and Colorimetry

Abstract

The colored perception of an object is a complex and totally subjective phenomenon involving numerous parameters, physicochemical as well as psychological. As has been seen, butterflies prove quite talented at drawing attention or hiding themselves. We will now consider the fellow creature, the predator, or more generally, the observer viewpoint. We will briefly introduce the physiology of the human eye and focus on the techniques to characterize colors, the stimulus, and the nervous message and its corresponding image in the brain.
