	Ewald Hering - Wikipedia, the free encyclopedia
		Hering looked more at qualitative aspects of color and said there were six primary colors, coupled in three pairs: red-green, yellow-blue and white-fl.
		Heinrich Ewald Hering attended the universities of Prague and Kiel, receiving his doctorate in 1893 at Kiel, where he worked in the institute for general and experimental pathology 1893-1898.
		Hering was not a very popular man, but he was an important medical scientist, recognized for his thoroughness and stubbornness.

	Ewald Hering: Just the facts... (Site not responding. Last check: 2007-10-21)
		Ewald Hering (August 5, 1834 - January 26, 1918) was a German physiologist (A biologist specializing in physiology) who did much research into color (A visual attribute of things that results from the light they emit or transmit or reflect) and spatial perception.
		Hering disagreed with the leading theory developed mostly by Hermann von Helmholtz (German physiologist and physicist (1821-1894)).
		Hering in turn believed that the visual system worked based on a system of color opponency.

	Ewald Hering
		Hering states that there are, in addition to fl and white, four colours which "can occur without a tinge of another colour" and recommends that "each visual perception" can be seen as a "mixture of the six basic sensations" which oppose each other and thus interact.
		Hering therefore concludes that there are not three but four elementary colour sensations or psychological primaries which code our perception by means of so-called opponent-processes.
		Hering's opponent-theory was not accepted, being criticised chiefly by students of Helmholtz who argued that Hering's proposal only made sense if two different processes existed within the nervous system: namely: stimulating and moderating processes.

		Initially proposed by a Ewald Hering, a nineteenth century physiologist, it drew its inspiration from the existence of opposing muscle groups.
		Hering thought that analogous opposing processes could explain some aspects of color perception, but the resulting theory was more complicated and less intuitive than that proposed by the great Hermann von Helmholtz.
		Hering thought that there are four fundamental colors, organized in two pairs: red vs. green, and blue vs. yellow.

		Hering challenged the colour-vision theory of Hermann von Helmholtz.
		Visual sensations, according to Hering’s view, were due to three colour receptors responding in an "opponent" fashion in colour-pairs (white/fl, yellow/blue, and red/green) to take account of the after-images of colours.
		Hering also is known for a classic optical illusion.

		The Opponent Color Theory of the 19th century physiologist Ewald Hering (Hering, 1964; Hurvich, 1981) derived by the analysis of subjective human color vision is in general correct, although the idea of opponent colors was described earlier by Goethe and Schoepenhauer.
		Hering's theory was brilliant but it was proposed when little was known about the anatomy and physiology of the retina.

	handprint : the geometry of color
		Hering pointed out that colored surfaces can produce a sensation of red mixed with yellow (orange) or red mixed with blue (purple), but do not produce the sensation of red mixed with green ("reddish green" or "greenish red") or yellow mixed with blue ("yellowish blue" or "bluish yellow").
		Hering also observed that we commonly lose color vision at night, yet still see light and dark, which convinced him that luminosity is separate from hue as a color vision process.
		Hering's examples (in the lower left corner) show that a mixture of 25% unique blue and 75% unique red produces a crimson red, while a mixture of 75% blue and 25% red produces a blue violet, and a 50%/50% mixture produces purple.

		The opponent color theory was first proposed by Ewald Hering in 1872 (Hering E., 1964).
		The opponent color theory suggests that there are three opponent channels: red versus green, blue versus yellow, and fl versus white (luminance), with each responding in an antagonist way.

	Guest editorial (Site not responding. Last check: 2007-10-21)
		Hering looked forward to the day when physiological psychology, including the physiology of consciousness, would replace the descriptive tradition of `philosophical psychology' which investigates the phenomena of sensation without regard for their organic basis.
		Hering will have to forgive me for not being able to say that I have been convinced by this `overwhelming proof' of the correctness of his theory, as he put it.
		Hering abandoned his theory of retinal depth values after this attack and adopted Helmholtz's view that stereopsis is based on binocular disparity.

	What is Color?
		Ewald Hering (1834-1918) devised the first accurate theory of color vision.
		This is conceptually similar to Hering’s circles, but the middle fades to gray.
		The artistic term “hue” is the edges of the square (the outside of Hering’s circle); “saturation” represents where the color is placed between grey middle and the colored edge; “value,” also called “brightness” or “luminance,” is the intensity of the color and is the third attribute.

		It erupted in Germany during the 1860s as a dispute between physiologists Hermann von Helmholtz, Ewald Hering, and their schools.
		Here R. Steven Turner explores the impassioned exchanges of those rival schools, both to illuminate the clash of theory and to explore the larger role of controversy in the development of science.
		Controversy, he suggests, is constitutive of scientific change, and he uses the Helmholtz-Hering dispute to illustrate how polemics and tacit negotiation shape evolving theoretical stances.

	Natural Color System - Wikipedia, the free encyclopedia
		The Natural Color System (NCS) is a perceptual color model published by the Scandinavian Colour Institute of Stockholm, Sweden.
		It is based on the opponent colors proposal by German physiologist Ewald Hering.
		This leads to the claim that the appearance of a color can be readily predicted from its NCS notation, whereas its notation in other systems such as RGB would sometimes look unintuitive.
