Retinex Theory of Color Vision- Santha Lakshmi Narayana

Webb10 apr. 2024 · The trichromatic theory of color vision says that human eyes only perceive three colors of light: red, blue, and green. The wavelengths of these three colors can be combined to create every color on the visible light spectrum. This theory was first suggested by Thomas Young and later tested by Hermann Von Helmholtz. WebbThis chapter presents the theories of color vision. The simplest hypothesis that fits the facts of color-matching is that there are just three photosensitive pigments used for color vision contained in three types of retinal cone. The cones may contain just one pigment each, or the three types may contain different mixtures of the three ...
