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).
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.
In subtractive (mixing paints, dyes, inks and natural colourants to create coloured) white only occurs in absence of pigments and using a support that colour while black results from the superposition of cyan colour, magenta and yellow. White light can be separated in every colour (spectrum) by a prism. In nature this decomposition leads to rainbow. In human vision, catch the light cones in retina of eye. There are three types of cones, each of which captures only the wavelengths indicated in graph. Transformed in brain correspond roughly with blue, green and red. Canes capture wavelengths indicated in curve R.
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.
This region, called visible spectrum, includes wavelengths from 380 nm to 780 nm (1 nm = 1 nanometer = 0.000001 mm). The light from each ofse wavelengths is seen in human brain as a different colour. Therefore, in decomposition of white light in all wavelengths by a prism or rain in rainbow, the brain perceives all colours. Therefore, the visible spectrum, which is the part of electromagnetic spectrum of sunlight can be seen, each wavelength is perceived in brain as a different colour. Newton first used the word spectrum (Latin for "appearance" or "apparition") in 1671 in describing his experiments in optics.
A normal human eye has only three types of receptors, called cones. They respond to specific wavelengths of red, green and blue 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.
