The first reason is to reduce fatigue. Because the blue mask can relieve doctors and nurses in the work of visual fatigue. Doctors and nurses usually wear white gowns. If they wear white masks, they will be "dazzling" in the light. In addition, blue is not easy to cause visual fatigue, so the mask will choose blue.

The second reason is that the blue cloth on the mask is treated with water repellent, so this layer of cloth needs to be worn outside. Then, the disposable mask is chosen in a bright blue color to remind the user that the face is facing outwards. In addition, disposable masks are divided into three layers of cloth, while the inside of the masks is white on both sides. If the outer layer is also white, then the manufacturer is prone to confusion in the production process. So avoid this by choosing a blue cloth. Combined with the above two points, most masks on the market are blue.
