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).
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.
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.
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.
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.
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.
