In the first paragraph, what two images does the narrator juxtapose for contrast? What are the connotations of these juxtapose images?

From the text:

When I think of the hometown of my youth, all that I seem to remember is dust—the brown, crumbly dust of late summer—arid, sterile dust that gets into the eyes and makes them water, gets into the throat and between the toes of bare brown feet.

And one other thing I remember, another incongruency of memory—a brilliant splash of sunny yellow against the dust—Miss Lottie’s marigolds.

In the first paragraph, the author juxtaposes the abundance of dust with the presence of beauty..... a bit of beauty in an otherwise ugly time..... the Great Depression.
