Everywhere we look, there is the color. We see it in the sky and in the sea, There is the color in rocks and in all plants and animals. The color makes our homes and schools pretty. We even see the color in our food. It makes things look good.
Everything we see has the color. We see green grass and red apples. How can we see colors? We see colors when light hits our eyes. Dogs and any other animals can't see colors. But bees can. They even see colors we don't see. This helps them find flowers to fly to.
We sometimes use the names of colors to say things. People may say "see red "when they are angry.
Or you may say you "feel blue". This means you are sad. We use colors to tell us things, too. Red means to stop. Green means to go.
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(色盲).
