Colors can be seen everywhere. We see them in the sky and in the sea. There are colors in rocks and in all plants and animals. Everything we see has colors. We see the colorful world. How can we see colors? We see colors when light hits our eyes. Dogs and many other animals can't see colors. But bees can. This helps them find flowers to fly to.      We sometimes use the means of colors to express our feelings. People may say that they see red when they are angry. Or you may say you feel blue. This means you are sad. We also use colors to tell us things. Red is the color of stopping signs. Green means that you can go.      Animals come in all kinds of colors. Many of these are very pretty. An animal's color may say "Here I am." or "Watch out". Or it may help the animal to hide. Some animals can make their colors similar to their surroundings (周围的事物). Then they can't be seen easily.      Some people can't tell one color from another. They can see yellow and blue. But they can't tell red from green. We say these people are color blind.
