This accurate information is transferred to visual cortex in ways called optical radiation. Colour perception is a result of activity of complex neurons of visual cortex area V4 / V8, specific to colour. This activity determines that the experiential qualities of colour vision may be referred by the attributes: brightness, hue and saturation (advanced color theory).
Is called photopic vision that takes place with good lighting conditions. This view enables the correct interpretation of colour by the brain. Many African mammals, such as humans, share the described genetic characteristics: why is said to have trichrome perception. However, mammals of South American origin have only two genes for colour perception. There is evidence to confirm that the appearance of this third gene was due to a mutation that one of two doubled original.
In subtractive (mixing paints, dyes, inks and natural colourants to create coloured) white only occurs in absence of pigments and using a support that colour while black results from the superposition of cyan colour, magenta and yellow. White light can be separated in every colour (spectrum) by a prism. In nature this decomposition leads to rainbow. In human vision, catch the light cones in retina of eye. There are three types of cones, each of which captures only the wavelengths indicated in graph. Transformed in brain correspond roughly with blue, green and red. Canes capture wavelengths indicated in curve R.
The vision is a sense that is the ability to detect light and interpret it. The vision is characteristic of having such a dedicated system she called animal visual system. The first part of visual system is responsible for forming the optical image of visual stimulus on the retina (optics), where the cells are responsible for processing information.
It is called additive to obtain a light colour determined by the sum of other colours synthesis. Thomas Young based on the discovery of Newton that the sum of colours of visible spectrum formed white light conducted an experiment with flashlights with the six colours of visible spectrum, projecting these foci and superimposing reached a new discovery to form the six colours of spectrum only took three colours and also adding the three light formed. Reproduction process normally used additive red, green and blue light to produce other colours. Combining one ofse primary colours in equal proportions with other colours produces secondary additives, lighter than previous cyan, magenta and yellow.
This region, called visible spectrum, includes wavelengths from 380 nm to 780 nm (1 nm = 1 nanometer = 0.000001 mm). The light from each ofse wavelengths is seen in human brain as a different colour. Therefore, in decomposition of white light in all wavelengths by a prism or rain in rainbow, the brain perceives all colours. Therefore, the visible spectrum, which is the part of electromagnetic spectrum of sunlight can be seen, each wavelength is perceived in brain as a different colour. Newton first used the word spectrum (Latin for "appearance" or "apparition") in 1671 in describing his experiments in optics.
Newton observed that when a narrow beam of sunlight incident on a triangular glass prism with an angle, a part is reflected and again passes through the glass and disintegrates in different colour bands. Newton also made to converge those same rays of colour in a second lens to form white light again. He proved that sunlight has all the colours of rainbow. When it rains and the sun shines every raindrop behaves just as Newton's prism and union of millions of raindrops phenomenon arc is formed iris.
When light strikes an object, its surface absorbs certain wavelengths and reflect others. Only reflected wavelengths can be seen by the eye and therefore in brain only those colours are perceived. It is a different natural light process that has all wavelengths, there whole process only has to do with light, now in colours we perceive an object also the object must be taken into account if that sleeps to absorb certain wavelengths and reflect others.
