In fact, not only the doctor's surgical clothes, but also the sheets in the operating room and the walls of the operating room are all green. However, with the development of the times, some hospitals have also adopted blue or navy blue as the main color tone, but the dark color is still the main color.

There are many interpretations of green: for example, green can reduce the visual fatigue of doctors and relieve the psychological pressure of patients, and green yearns for vitality and life.

With the development of the times, hospitals began to try more colors. For example, green and blue are very mainstream colors. As for why we choose the dark color department, we can imagine that if the doctors are all in red surgical clothes, the red operating room, and the doctors' surgical instruments, it seems that there is a sense of haunted house. The patient's blood pressure soared after entering the hospital, and at the same time, he was afraid of the doctor, which would definitely have adverse effects on the operation.
