People may easily ignore that we are living in a world full of different colors,such as red,blue,green,black,pink and so on.We can never tell how many kinds of them are there.But we all know that colors are very important in people's life.
The sky is blue and white.The trees are green and yellow.We can even say that spring is freshing green,summer is hot blue,autumn is golden yellow and winter is cold white.If one day all the colors disappear,what will it be to live in this world.We feel bored.We can't even tell the differences between the sky and land,between trees and houses.
The world is colorful.And we can't live without colors.
