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).
A lot of waves (colours) affect the pigment that absorbs green and red light and reflects only the blue, creating the blue. A pigment or a dye is a material that changes the colour of reflected light because light waves selectively absorb certain. White light is approximately equal to a mixture of entire visible light spectrum.
When this light encounters a pigment, some waves are absorbed by chemical bonds and substituents of pigment, while others are reflected. This new spectrum of reflected light creates the appearance of colour. For example, a dark blue pigment reflects blue light, and absorbs other colours.
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.
Individuals and members of other species that have these three types of receptors are called trichromats. Although the maximum sensitivity of cones is not exactly at the red, green and blue frequencies, are the colours that are chosen as primary, because they can stimulate the three colour receptors almost independently, providing a wide gamut.
