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).
The reflected waves are captured by the eye and interpreted in brain as different colours depending on the lengths of corresponding waves. The human eye can only perceive wavelengths when light is abundant. In low light is in black and white. In so-called additive synthesis (commonly called "colour overlay light") white colour results from the superposition of all colours, while black is the absence of colour.
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.
The first to intervene are photoreceptors, which capture the light that strikes them. They are of two types: rods and cones. Other retinal cells are responsible for transforming said light into electrochemical impulses and transport them to optic nerve. From there, projecting the brain. In brain process of forming the colours and rebuild the distances, movements and shapes of observed objects is performed.
Many birds and marsupials are tetracromatas, and it has been suggested that some women are born, June 5 with an extra receiver for yellow. Furthermore, most mammals have only two types of colour receptor and therefore are dichromats; for them, there are only two primary colours. Everything that is not additive colour is subtractive colour. In other words, everything that is not direct light is light reflected from an object, the first is based on additive synthesis of colour, the second subtractive synthesis of colour.
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.
This is because brain activity retinal since photoreceptors, although simple, are neuronal cells. Information of rods and cones is processed by other cells located immediately below and connected behind them (horizontal, bipolar, amacrine and ganglion). The processing inse cells is the source of two-dimensional or antagonistic pairs chromatic channels: Red-Green - Blue - Yellow and an achromatic channel dimension or chiaroscuro.
