What make skin color of human beings different each other? The explanation is on the series of chemical processes, which take place in human body and their layer skin. In the layer of skin, there is a chromogen, it is a basic color substance, and basically it’s colorless, however if a certain ferment or enzyme affects the basic color substance, a certain skin color will be formed. Human skin itself, without the existence of the basic color substance, is ivory white (we call the person as an albino). But then, there is an added color For example : yellow color in the skin make yellow color in the skin, other variety of skin colors also exists in black color skin. It is due to the existence of the subtle granules from the substances called melanin. Melanin has a similar color with a squid. Yet, because of the great pile of the substance, to our vision our skin looks black. Another color shadow can be added to the skin by the red color of the blood which circulates all around the body under the network of skin layer.
So, human skin color depends on the amount of the four basic substances, i.e. white, yellow, black and red. Those colors group and form a certain color impression. All human skin colors from different nations can be formed from a combination of different basic color which all men have.
