     Long, long ago, seven colors were arguing about who was the most important color.

     Red said, "I am the ruler of all of you. I represent blood-life's blood! Without me, the world would be

empty." Orange said,"I am the color of health and strength. I am so beautiful that no one can think of any

of you." Yellow said, "I bring laughter and warmth into the world. Without me, there would be no fun."

     Green said, "I am the most important. I am the sign of life and hope. Without me, all animals would die."

Blue said,"You only think about the earth, but forget the sky and the sea. Water is the basis of life. Without

me, you all would be nothing." Purple said,"I am the color of royalty, power and wisdom. People usually

listen to me." Indigo (靛蓝) finally said, "Don't forget me! I am the color of silence. You need me for balance."
