How does Langston Hughes use imagery in Not Without Laughter?

Imagery:

"Being colored is like being born in the basement of life, with the door to the light locked and barred—and the white folks live upstairs. They don't want us up there with them, even when we're respectable like Dr. Mitchell, or smart like Dr. DuBois.... Maybe it's best not to care, and stay poor and meek waiting for heaven like Aunt Hager did .... But I don't want heaven! I want to live first! ... I want to live!"

"Sandy stood on the front porch looking at the morning star as the clatter of the horses' hoofs echoed in the street."
