    Once the colors of the world argued. All thought that they were the best and most important.

    Green said, "Clearly I am the most important. I am the sign of life and hope. I'm the color of grass, trees and leaves. Without me, all animals would die."

    Yellow laughed, "You are all so serious. I bring happiness and warmth into the world. Every time people look at a yellow sunflower, they start to smile. Without me there would be no fun."

    Orange shouted, "I am the color of health and strength. I have the most important vitamins. Think of carrots, vegetables and oranges. When I appear in the sky, everyone is shocked at my beauty and nobody gives another thought to any of you."

    Red couldn't stand it any longer. "I am the color of danger and bravery. I bring fire into the blood."

    Their voices became louder and louder. The thunder got angry and the rain started to pour. When they became calm, the rain said, "You foolish colors. Don't you know that each of you is special? If you don't agree, just follow me." They did as the rain told them and together made the most beautiful rainbow.
