P.1 2nd paragraph: "Any pattern of excitation among
cones can be matched by an appropriate mix of three primary lights, and this is the basis for RGB color
display devices. Cone signals get processed by several circuits in the retina and beyond. This system
ultimately has limited resolution, and in practice human subjects can distinguish about 1–2 million
different colors (primary source). Clearly, a quantitative understanding of color perception has
both energized the search for the underlying neural circuits and made possible the design of image
display technologies that mimic reality." See BNID 107061 |
