Do you eat less if you use a blue plaque?
Some restaurants have special blue used for the plate because they believed that they served food on blue plates, customers were eating less.
Assume that the blue color makes a person less hungry. So, theory, eating a plate blue course you want to eat less. Same goes if you paint the inside of your refrigerator blue. The theory is based on the fact that most items in nature that are blue are not edible (blueberries being the exception) and, therefore, we are programmed to not eat blue things because we do not want to die. On the other hand, yellow, red and orange make us hungry. You noticed that the channels fast food colors to use?
