In the first paragraph, what two images does the narrator juxtapose for contrast?

The author contrasts the dry, dirt roads and grassless yards with the brilliant spash of yellow provided by Miss Lottie's marigolds.

And so, when I think of that time and that place, I remember only the dry September of the dirt roads and grassless yards of the shantytown where I lived. And one other thing I remember, another incongruency of memory—a brilliant splash of sunny yellow against the dust—Miss Lottie’s marigolds.
