How many skin tones do humans have? How many people of color are there in the world?

There are four colors of people in the world. They are Caucasian, Yellow, Black, and Brown.

The color is determined by the amount of melanin in it. In the alpine northern Europe (boreal zone), people are not exposed to the scorching sun, and the body has very little melanin, so the skin color is mostly white.

Due to the tropical areas where the sun is concentrated at the equator, it is often exposed to strong sunlight (ultraviolet rays), and the body is adjusted to produce a large amount of melanin, so that it is protected **, which is black or brownish-black; Temperate zones are neutral yellow or brownish yellow – (melanin).

Ethnicity is affected by skin color

The genetic characteristics of skin color are one of the indicators of racial classification, but there are still large differences in skin color within the three major human races. For example, the Caucasian race includes Europeans, Arabs, and Iranians, among which Europeans have the lightest skin tone; East Asian races include people from Central, East and Southeast Asian countries, and Southeast Asian residents have significantly darker skin tones.

There are six skin tones in the world, namely red, yellow, brown, blue, black and white, which is mainly due to the different amounts and distribution of melanin in the world. Melanin is a protein derivative that is brown or black in color and is produced by melanocytes.

Due to the different amounts, sizes, types and distribution of melanin, different skin tones are determined.

The melanin in the yellow race** is mainly distributed in the basal layer of the epidermis, and less in the spinous layer; In black people, there is a large amount of melanin in the basal layer, spinous layer and granular layer; The distribution of melanin in Caucasians** is the same as in yellow people, except that the amount of melanin is less than that in yellow people.

Yellow people have a pale yellow complexion; Black people have dark complexions; Caucasians' skin tones are light and pale in color.

So, why are there people of different skin colors in the world?

The color is mainly determined by the amount of melanin in it. Melanin is a black or brown particle, and its main role is to block the damage of ultraviolet rays in the sun's rays to the cells below the human body**. When the sun is stronger, the amount of melanin increases, so we get tanned in the summer.

The color of human beings is the result of adaptation to nature in the process of evolution. Africans living in the equatorial region, due to ** are often strongly affected.

When exposed to sunlight, a large amount of melanin is produced in the body, so Africans** are black. In the alpine land less, so, ** is white. Yellow people generally live in temperate regions, the intensity of sunlight is in the middle, and melanin is also in between, so the color of ** is also between the two people.

Scientists have found that there is no difference in the ancestors of human beings at the beginning, and the skin color is basically the same. It was only later that people moved to different regions and gradually developed differences in skin color in order to adapt to the outside environment.
