Red is hot. No, not right now, but all the time. Red has always been an important color. It is one of the colors we choose most often to symbolize something, making it one of the most common of all colors in national flag designs. The color red is also the color of blood, our life force, so it’s no wonder that we’re attracted to it. Red energizes us and makes us hungry. That’s why so many fast food restaurants use the color red in their designs and logos. Red is also a popular color for dining rooms; it keeps us enjoying the food and makes our dining experience livelier.
