The sky is blue. The sun is bright. A small cloud floats high. Her name is Cloud.
Cloud is white. She is thin. She feels cold. "I need a coat," Cloud says. She looks down at the world. She sees the green grass. She sees the blue sea. She sees the tall trees.
Cloud moves fast. She meets the wind. "Wind, please help," says Cloud. "I want a new coat." The wind blows hard. He brings gray mist. The mist covers Cloud. Now, Cloud is gray. She feels warm. She feels heavy.
"I look different," Cloud says. She looks at the ground. She sees flowers. The flowers are dry. They need water. Cloud is sad. She wants to help.
Cloud opens her coat. Rain falls down. The rain hits the grass. The flowers drink. The trees drink. The world becomes green and happy.
Cloud is light again. She is white. She is thin. She does not need a coat now. She is happy to help the world grow. She floats away in the blue sky.
What color is the cloud at the end of the story?
