Color processing in the primates Essay -- Biology, Visual System, Colo

Color is a feature that is possess by very few mammals. K .Tansely in one of his books on visual system the vision in vertebrates commented that On the whole mammals wait not to have color vision, except for the primates where it is well actual and almost certainly trichomatic. The word trichomatic was derived from a theory given by French physiologist Palmer in 1777 which stated the presence three different types of numberless number of molecules present in the valet de chambre retina. These types are for detection of colours like red, blue and yellow. Few years later Thomas juvenile postulated the presence of three types of cones which are responsible for the detection of these primary colorize or metamers and their concept of empirically proven by Maxwell in 1860. This trichomatic nature of intelligence of military man retina seemed a limitation as human eye can perceive millions of colorise. These millions of change are limited to a Grassmans laws explained addit ive, scalar and associative properties of metamers to prove the different combinations of colors comprehend by visual system. The human range of light of light is from 380nm to 760nm. The perception of color depends upon photo-receptors ability to segregate different wavelength. The Bowmaker et al in 1979 was cap qualified to identify the cone using micro-spectrometry by seeing cone immersion spectrum.The cones were in blue, green and red spectrum with wavelength of 420nm, 534 nm and 564 nm. The rod that was identified mantled the spectrum at 498 nm. The results on the ducking spectrum were quite similar to the results found on Rhesus monkey by the same author. *Bowmaker et al.The name given to cones on the absorption spectrum are S(Short), L(Long) and (M) moderate .
