Dichromatic theory

Dichromacy (from Greek di, meaning "two" and chromo, meaning "color") is the state of having two types of functioning photoreceptors, called cone cells, in the eyes. Organisms with dichromacy are called dichromats. Dichromats require only two primary colors to be able to represent their visible gamut. By … See more Dichromatic color vision is enabled by two types of cone cells with different spectral sensitivities and the neural framework to compare the excitation of the different cone cells. The resulting color vision is simpler than typical … See more • Pentachromacy • Mantis shrimp (dodecachromats) • RG color space See more • Visual comparisons of various types of color vision impairments by Cal Henderson • Colblindor -- Color Blindness Viewed Through Colorblind Eyes by Daniel Flück See more Dichromacy in humans is a form of color blindness (color vision deficiency).

Web1. INTRODUCTION A dichromatic graph is a complete graph with n vertices (an n-cIique) with each edge colored in one of two ways, for instance, either red or blue. A (k, l) coloring is one in which no k-clique is completely red, and no Lclique completely blue. Dichromatic properties can be explained by the Beer–Lambert law and by the excitation characteristics of the three types of cone photoreceptors in the human retina. Dichromatism is potentially observable in any substance that has an absorption spectrum with one wide but shallow local minimum and one narrow but deep local minimum. The apparent width of the deep minimum may also b…
