Often times known as Chromatics, the science of color is a very abstract and interesting subject that discusses the visual perceptual property that corresponds in humans to various colors. These colors deriving from the spectrum of light then interact with the eye through light receptors. This complex connection that is made from our eyes to our brains is due to the brains perceptions that vary through spectral sensitivity, as colors stimulate these types of cells; the physical or psychological effects of color are produced. The ability for the human eye to distinguish these colors is based upon the varying sensitivity of the retina. The retina has three different types of color receptor cells, each of which help distinguish the various shades of color and how they reflect in certain conditions. The brain then uses either of these three channels to distinguish what type of color your brain should view the shade to be, as yellow receptors will go through their specific channel, just like black would attempt to go through theirs. The idea of color science is vast and complex as scientists are attempting to understand the theory of color and how it works closely with the concept of color abstractions through which your brain works with them. As these studies of color have proven to be valuable insight into how the brain works and responds with what it envisions.
Psychologically the brain and eyes work together, as the eyes carry the signal and transmits it to the brain, the vision of color grants our brain to work and view each color in a different way, and therefore interpret them. This is known as psychological symbolism, as some colors provoke sensations of anger, pride, happiness, or relaxation. Colors have significant impact on our brains, and therefore can affect our emotions. Although there is still much debate as to how colors can signify and provoke the brain to work in a certain way. Many scientists believe that the source of the meanings could be found in nature, genes, or even socialized to us at an early age. Aside from having actual emotional impact, colors can also signify or tell our brains something to do such as an action otherwise known as natural association. Seeing things in red generally make an individual motivated, a blue light bulb within a refrigerator indicates to our brain to eat less, and using a purple pen when drafting essays or drawings has been thought to bring out more creativity.
