Lippmann won the Nobel Prize in Physics in 1908 "for his method of reproducing colours photographically based on the phenomenon of interference". [ 3 ] Images made with this method are created on a Lippmann plate : a clear glass plate (having no anti-halation backing ), coated with an almost transparent (very low silver halide content) emulsion ...
The discovery of dye sensitization by Hermann Wilhelm Vogel in 1873 greatly facilitated the initial three-color analysis on which all of Ducos de Hauron's methods depended. [ 4 ] The most widely reproduced of his surviving color photographs is the View of Agen , an 1877 image of a landscape in southern France, printed by the subtractive ...

Chromolithography is a chemical process based on the rejection of water by grease. The image is applied to stone, grained zinc or aluminium surfaces, with a grease-based crayon or ink. Limestone and zinc are two commonly used materials in the production of chromolithographs, as aluminium production was limited before the invention of the Hall ...
Autochrome is an additive color [3] "mosaic screen plate" process. The medium consists of a glass plate coated on one side with a random mosaic of microscopic grains of potato starch [6] dyed red-orange, green, and blue-violet (a variant of the standard red, green, and blue additive colors); the grains of starch act as color filters.
The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels , each comprising an opposing color pair: red versus green , blue versus yellow ...
This discovery has generated interest and discussion among scientists because it raises important questions about the evolutionary pressures that led to the development of color vision. Early forms of color vision may have been utilized for activities such as foraging, mate choice, or avoiding predators, even in a less colorful world. [11]
Color is an element consisting of hues, of which there are three properties: hue, chroma or intensity, and value. [3] Color is present when light strikes an object and is reflected back into the eye, a reaction to a hue arising in the optic nerve. [6] The first of the properties is hue, which is the distinguishable color, like red, blue or ...
