Men are more apt to say brown is one of their favorite colors. In the U.S. flag , white stands for purity and innocence. Red represents valor and hardiness, while blue signifies justice, perseverance, and vigilance. The stars represent the heavens and all the good that people strive for, while the stripes emulate the sun's rays. While blue is one of the most popular colors it is one of the least appetizing.
Blue food is rare in nature.
Food researchers say that when humans searched for food, they learned to avoid toxic or spoiled objects, which were often blue, black, or purple. When food dyed blue is served to study subjects, they lose appetite. Green, brown, and red are the most popular food colors. Red is often used in restaurant decorating schemes because it is an appetite stimulant.
