Everywhere we look, there is colour. We see it in the sky and in the sea. There are colours in all plants and animals. Colour makes our homes and schools pretty. We see it in pictures and in books. We even see colour in our food. It makes things look good.

How can we see colour? We see colour when light hits(射入)our eyes. Dogs and many other animals can’t see colours. But bees(蜜蜂) can. They even see colours we don’t see. This helps them find flowers to fly to.

We sometimes use the names of colours to say things. People may say that they “see red” when they are angry(生气). Or you may say you “feel blue”. This means you are sad. We use colour to tell things., too. Red is the colour of stop signs. It means to stop. Green means to go.

Animals come in all kinds of colours. Many of these are very pretty. An animal’s colour may say “here I am”., “stay away” or “be careful” or it may help the animal hide(隐藏). Some animals can make their colours look like the trees around them, then other animals or people can not find them.
