Theory of Color Vision

  • Leon Gunther


In Chap. 13, we saw that one can characterize a light source in terms of its spectral intensity. We now turn to the question as to the relationship between the objective characteristics of a light and the subjective perception of the light. We have already identified three attributes of one’s visual perception – hue, saturation, and brightness. The first two are the attributes that, together, are referred to as the color. Thus, our goal is to establish the relationship between the spectral intensity and these three attributes. We will first summarize this relationship as it was determined through years of testing many individuals. Then we will discuss how this relationship can be understood in terms of the biophysical behavior of the visual apparatus, the rods of the retina.
