The trichromatic theory of color vision is also known as the Young-Helmholtz theory, named after Thomas Young and Hermann von Helmholtz who proposed that the eye has three types of color receptors (cones) that are sensitive to short (blue), medium (green), and long (red) wavelengths. The brain then combines the signals from these receptors to create our perception of color. The other named theories, Seurat-Signac and Young-Adhart, do not pertain to color vision. The Hering theory, on the other hand, is an opponent-process theory that suggests that color vision is based on opposing pairs of colors (red-green, blue-yellow, black-white) that result from the activity of neurons in the visual system.
