People may easily ignore（忽视） that we are living in a world full of different c{#blank#}1{#/blank#}, such as red, blue, green, black, v{#blank#}2{#/blank#} and so on. We can never tell how many kinds of them there are. But we all know that colors are very important in people's e{#blank#}3{#/blank#} life.

The sky is blue and white. The trees are green and yellow. We can even say that s{#blank#}4{#/blank#} is freshing green, summer is hot blue, autumn is golden yellow and winter is c{#blank#}5{#/blank#} white. I{#blank#}6{#/blank#} one day all the colors d{#blank#}7{#/blank#}, what will it be to live in this world. We feel bored. We can't even tell the d{#blank#}8{#/blank#} between the sky and land, between trees and houses.

The world is c{#blank#}9{#/blank#}. And we can't live w{#blank#}10{#/blank#} colors.
