When the Olympic Games were in full swing, the streets and parks of Paris occasionally flashed with beautiful colors, becoming a beautiful scenery. Clothes of different colors, women from different countries, for the same grand event, come to the romantic capital for the same grand event, presenting different colors to the world.
 
Freedom, passion, and exuberance are the calling cards of Paris, and also the calling cards of colors. But how is color perception formed and perceived by us? People have approximately 6-8 million cone cells, and there are three types of cone cells that are most sensitive to the three primary colors of red, green, and blue. Different shades of light can cause varying degrees of excitation in cone cells, resulting in different colors of visual perception.
 
Each type of cone cell can distinguish 100 colors, and a total of 1 million colors can be distinguished by three types of cone cells. Some women have a fourth type of cone cell, which means they can see 100 million colors, which is quite incredible.1 million colors, a person's entire life cannot see them all, let alone 100 million colors. We can say, 'Color with infinite possibilities.'
