The colour is a visual perception that is generated in brains of humans and other animals to interpret nerve signals that send the photoreceptors in retina of eye, which in turn interpreted and distinguish the different wavelengths that capture the visible part of electromagnetic spectrum (light)(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 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.
The cones are light quanta accumulators, which transform this information into electrical impulses of organ of sight. There are three kinds of cones, each of which has a photopigment that only detects a specific wavelengths about the wavelength converted in brain correspond to blue, red and green. The three groups of mixed cones allow to form the full spectrum of visible light.
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.
