Module 9: "Color stimuli"
  Lecture 24: "Effect of Color in Food & Beverage"
 

Red is an appetite stimulant. There are plenty of red foods, from tomatoes, to strawberries and red peppers. Red also stimulates conversation, so it’s no surprise restaurants want to incorporate it into their color scheme. You’ll eat a lot and enjoy your conversation.

Orange is associated with need and hunger. Oranges, carrots and salmon come to mind. Orange is commonly used in restaurants as well, because like red it stimulates hunger, and restaurants want you to eat.
Yellow is a sociable color. Lighting can adversely affect the yellow, so be careful how bright you go with it. Bright yellows are used liberally in fast food restaurants – think McDonald’s. I wonder if they want you to focus more on talking and less on what you’re eating.
Beige and Brown are earthy tones that create a calming atmosphere without suppressing appetites. Deep browns, dark woods for example, can make a room feel luxurious. These are also some of the most common colors in the foods we eat, apart from red and green, and it makes sense. Think meat, bread, and beans – protein and carbohydrates are important to our diets. Do you think deep browns feel luxurious, because it reminds you of a nice steak?
Green is a soothing color that aids digestion. It is also known to help you focus. Perhaps if you eat your vegetables, you’ll feel relaxed and get more done. Restaurants can use green in their décor to create a soothing ambiance, setting them apart from a stimulating restaurant done in red or orange.
Blue is known to be a calming color, and a favourite of many. But when it comes to food, it isn’t as popular. Blue acts as an appetite suppressant. If you want to eat less, try putting a blue light in your refrigerator or eating from a blue plate. How many blue foods can you think of that occur in nature? Blueberries are the only thing that comes to mind.
