What do Helen, Bob and Alice talk about? Let's have a look!

Eleven-year-old Helen

There are many colors, like white, blue, orange and red. But my favourite colour is green. Green is the colour of life. Green is good for eyes, too.

Twelve-year-old Bob

My jacket, quilt and cup are blue. Blue is the colour of the sky. When the sky is blue, we are happy to have a nice day. Blue is also the colour of the sea. I like swimming in the sea. It's my favourite sport. What colour do I like? Do you know now?

Nine-year-old Alice

I love white best. White is the colour of snow. After a snow, everything is white. I think it's a clean colour. I can play with snowballs with my friends.

Now can you tell me what colour you like?
