Why do doctors and chefs wear white clothes?

Chef: White stands for hygiene. Because the clothes are white, you can clearly see whether they are dirty or not, and always remind the chef to pay attention to hygiene.

Doctor: Medical personnel need a clean environment most, and any pollution should be found in time. However, colored clothes will cause visual interference and affect the human eye to find pollutants, especially those attached to the body. Therefore, medical staff wear white coats and always supervise the cleanliness of the medical environment.
