When viewed under white light, it appears red. But this does not mean that emits red light, which would be the case an additive synthesis. Doing so, we would be able to see in dark. Instead, absorbs some wavelengths that comprise the white light, reflecting only those human seen as red. Humans see red apple due to the particular operation of your eye and brain interpretation of information coming at you in eye (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.
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.
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.
