White is the color most associated with cleanliness. Objects which are expected to be clean, such as refrigerators and dishes, toilets and sinks, bed linen and towels, are traditionally white. White was the traditional color of the coats of doctors, nurses, scientists and laboratory technicians, though nowadays a pale blue or green is often used. White is also the color most often worn by chefs, bakers, and butchers, and the color of the aprons of waiters in French restaurants.[44]
