Young-Helmholtz theory of color vision
Etymology: Thomas Young, English physician, 1773-1829; Hermann L.F. von Helmholtz, German physician, physicist, and physiologist, 1821-1894
the concept that all color sensations are mediated by three types of retinal receptors, which correspond to three primary colors: red, green, and blue-violet. By their individual and combined activities, the receptors produce the perception of all visible hues.
