When it comes to food and beverages, color affects aesthetics, flavor and identification, perception, and anticipated taste. Color psychology teaches us that our senses have an even broader influence – they are connected to emotional reactions and can influence our appetite. Let’s look at the psychology associated with colors of products we view every day.

Red
Red is an appetite accelerator. It represents health, vigor, and love. This color has been found to stimulate senses and raise blood pressure. People tend to gamble more and make riskier bets when seated under a red light as opposed to a blue light.   Red - Beverage Industry.

In addition, blue relaxes the nervous system.  Blueberries - Beverage Industry.
