At present, the color of surgical gowns is mostly dark blue or green. Usually one-time blue with green fabric. These colors do not easily cause visual fatigue, and blood stains do not form obvious contrast.

In fact, the main reason surgeons use blue and green surgical gowns is that these two colors are complementary colors to the body's internal organs and blood. Not only does white cause glare, it can also create an optical illusion known as an afterimage.

As surgeons race against time to focus on surgery, they will be keeping a close eye on the body's red guts. As we all know, the degree of "redness" of each organ in the human body varies from deep to light. As the surgery progresses, the human eye's ability to detect "red" will gradually diminish. The result is "oversaturation". If they look at their colleagues in white, or glance at a white wall, they will often see a teal "ghost." Imagine seeing a green intestine on a colleague's white coat...these bluish-green afterimages can impair a surgeon's vision and judgment, and they won't be able to recognize subtle red differences between different sites. Under such visual interference, doctors may make unnecessary mistakes. After staring at red for a period of time, the brain becomes particularly sensitive to cyan. However, with the blue-green surgical gown, the red back image does not stand out in the background, which not only does not affect the doctors' surgery, but also improves their sensitivity to red, which can be said to kill two birds with one stone. Therefore, when people understand the principles of complementary colors, they will no longer use white surgical gowns.

At present, surgical gowns have basically maintained their unique and simple style. Short-sleeved V-neck jacket, loose pants, easy to wash and wear, good breathability and comfortable feel. Doctors and nurses who perform the surgery also don surgical gowns during the procedure. Most of these clothes were made of pure cotton and were accidentally stained with blood or liquid. They felt heavy and wet.
