What color are the eyes of China people?

Non-immigrant countries in Europe, basically northern Europe and western Europe have more blue-green eyes, some brown eyes and a few gray eyes. In eastern Europe, about half are blue or green, and half are brown eyes.

Spain, Portugal and Italy in southern Europe mainly have brown eyes.

South America is basically brown-eyed, and Latin Americans (Hispanic or mixed with South America) are basically brown-eyed.

Black people are similar to Asians, with black eyes and brown eyes.

The iris of human eye consists of five layers: endothelial cell layer, anterior limiting membrane, matrix layer, posterior limiting membrane and posterior epithelial layer. Among these five layers of tissues, there are many pigment cells in anterior limiting membrane, stroma layer and posterior epithelial layer, and the amount of pigment contained in pigment cells determines the color of iris. The more pigment contained in pigment cells, the darker the iris and the darker the eyeball. The less pigment contained in pigment cells, the lighter the iris color and the lighter the eyeball color. The pigment content in pigment cells is consistent with skin color, which is related to the genetic relationship of race. Orientals are colored people, and the iris has a lot of pigment, so the eyes look black. Westerners are white, the iris has a little pigment, and the blood vessels are distributed in the matrix layer, so the eyes look light blue or green. Q:
