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.
In animal kingdom mammals generally do not distinguish colours well, birds however, yes; but usually have a preference for reddish colours. Insects, by contrast, tend to have a better perception of blues and even ultraviolet. Generally nocturnal animals see in black and white. Some diseases such as colour blindness or colour blindness from seeing colours well.
The first to intervene are photoreceptors, which capture the light that strikes them. They are of two types: rods and cones. Other retinal cells are responsible for transforming said light into electrochemical impulses and transport them to optic nerve. From there, projecting the brain. In brain process of forming the colours and rebuild the distances, movements and shapes of observed objects is performed.
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.
