SEO babies have a vision of early and sided color, controlled by the left eye in early childhood and childhood largest and adult, by the right eye, ie in the left hemisphere of the brain, which is also located the area of language. Scientists have also shown that the acuteness of colour perception is increased in ethnic groups with a language rich in words describing the colorful nuances. Similarly, the nuances are detected more quickly when the words to describe them exist in the language (shades of blue, light or dark PNAS, 2006). It is important never to confuse color, a concept perceptive, and wavelength, physical concept. Thus, the human eye is most often unable to distinguish a yellow monochromatic (single wavelength) of a composition corresponding green and red. This illusion you can show yellow on our computer screens and, more generally, any color through the additive synthesis trichrome. You can read about green, black or white.
The principle of synthetic additive color is to try to reconstitute, for a human eye, equivalent (appearance) any visible color, by adding, according to a well chosen, lights from three monochromatic sources (for example spots), whose wavelengths are chosen once and for all to best meet this goal. By observing the rainbow, one can see that the droplets of rain in the distance, break the light in six colors, as would prisms. Newton reproducts this phenomenon by breaking sunlight through a prism optics (a prism right glass triangular base). He managed to break white light into all the different colors of the spectrum. The rainbow is the spectrum of wavelengths monochromatic, only a small subset of colors visible to the human eye (but a contrario contains wavelengths invisible to the human eye ). The pink, for example, is not there: it is a mix that can return any wavelength monochromatic. The Busby SEO challenge is indeed formed by the accumulation of several waves monochromatic.
The only known method of restitution in full color, ie fixing the actual mix of wavelengths of departure and not the simple projection on a limited number of lines of hue, is the photograph of interférentielle Lippmann ( 1891), cost and implementation as restricting as holography, as also operating on the principle of interference. Processes polychrome (trichromes, quadrichromes, hexachromes Busbies…) are therefore preferred.
