First, blue. Blue brings people a sense of freedom. When people see the blue ceiling or building as soon as they enter the door, they will immediately become comfortable and can temporarily forget their previous unhappiness and troubles. When customers forget their previous troubles, they will naturally be in the mood to enjoy the food in the restaurant.
Second, red. Red will give people a feeling of burning enthusiasm. Even in hot summer, people have no appetite to eat, but when they enter the restaurant and see the bright red decoration style, they will unconsciously associate spicy and attractive food, thus stimulating their taste buds and making them want to taste the food in the restaurant very much.
