The Science of Color

In the 1960s, British physicist and mathematician Isaac Newton began a series of experiments on sunlight and prisms. He proved that clear white light consists of seven visible colors.

By scientifically constructing our visible spectrum (the color visible in the rainbow), Newton provides a way for others to try out colors in a scientific way. His research brings a significant breakthrough in the study of optical, physical, chemical, sensual and natural colors.

Aristotle developed the first known theory of the color God sent from heaven through the light of heaven. He suggests that all colors come from white and black (brightness and darkness) and associate them with four elements - water, air, earth and flame. Aristotle's belief in color has been widely used for more than 2000 years, until it is replaced by Newton.

Can you see the numbers in the circle? 5% of the population can not see the whole visible spectrum, this is known as color vision abnormality or color vision abnormality. Ishihara Plate is used to test color blindness of various types of patients.

Can you find animals hidden in this picture? Camouflage hides shapes by causing illusion using color. American artist Abbott Sayer introduced the concept of destructive patterns in which non-uniform marking of animals can hide their contours. In this figure, Thayer shows how the peacock disappears to the surroundings.

Thayer is an American artist seeking to understand that animals hide nature to survive. In his book "Invisible coloring of the animal kingdom", Thayer suggests a belief in protective coloring which is an important element in the evolutionary role that helps animals make myself appear as a predator. He has received a lot of praise and criticism. His view is extreme, I believe that all animals are colored for protection purposes, and do not recognize other possible causes such as sexual choice, that is, the characteristics of attracting spouses. Teddy Roosevelt most notably pointed out that this concealment depends on one freeze moment rather than continuing throughout the whole season or even throughout the day. Despite these drawbacks, Thayer continued to be the first person to disguise for military purposes. His proposal was initially dismissed but his former student was one of the founder of the American Disguise Association in 1916 and his theory was eventually adopted and still in use today.

The color pattern on the plane of Germany during the First World War was called diamond camouflage. That destructive model uses Abbott's theory to prevent enemies from observing the air and the ground.

Color science is sometimes called color science, colorimetry or simple color science. It includes the color perception of the human eye and the brain, the color source of the material, the theory of the color of the art, and the physical properties of the electromagnetic radiation in the visible region (often referred to simply as physics of light). ) Most light sources emit light at many different wavelengths; the spectrum of the light source gives a distribution of its intensity at each wavelength. The spectrum arriving at the eye from a given direction determines the color perception in that direction, but there are more spectral combinations than the light color perception. Indeed, colors can be formally defined as the type of spectrum that produces the perception of the same color, but these categories vary greatly from species to species and not so much between individuals of the same species. In each such class, the member is called the metamer of the color of the problem.

It is color. What is color? According to science, the color we interpret is due to electromagnetic radiation of different wavelengths between 390 and 700 nm in length. This range is called "visible spectrum". At about 450 nm, we see blue. But what happens if the blue I saw and the blue you saw were different? What happens if the brain looks at the difference in wavelength of light and assigns a random color to each specific wavelength? If I first saw blue, my brain would choose what you call green. What if our brain assigns colors to different wavelengths, but it is totally relative and personal? If you put your consciousness on my head, you can see the big screen on my visual cortex and you can see what I call blue, It may be obvious that it is another shadow
