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.
Within electromagnetic spectrum all possible energy levels of light form. Speaking of energy is equivalent to speak of wavelength; therefore, the electromagnetic spectrum covers all wavelengths of light can be. Across the spectrum, the portion that humans can perceive is very small compared to all existing.
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.
A normal human eye has only three types of receptors, called cones. They respond to specific wavelengths of red, green and blue light.
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.
