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 other words, these cells are excited or inhibited at the higher signal intensity versus Red Green and Blue to sum of Red and Green, also generating an achromatic path information related to luminosity. The information in this processing moves through the optic nerve to lateral geniculate nucleus (located on the left and right thalamus), where neuronal activity specific regard to suggestion of colour and chiaroscuro.
The appearance of pigments or dyes is closely linked to the light they receive. Sunlight has a high colour temperature and a relatively uniform spectrum, and is considered a standard for white light. Artificial light, meanwhile, tends to have large variations in parts of its range. Seen inse terms, pigments or dyes of different colours look. The dyes used for colouring materials such as fabric, while the pigments used to cover a surface, such as a box. From glaciations human employing plants and animal parts for natural dyes with which coloured their tissues. Then the painters have prepared their own pigments.
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.
By varying the intensity of each colour light finally reveals the full spectrum ofse three lights. The absence of three gives the black, and the sum of three gives white. These three colours corresponding to three sensitivity peaks of three colour sensors in our eyes. Primary colours are not a fundamental property of light, but a biological concept, based on the physiological response of human eye to light.
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.
