Imagine a talk between a man and a woman on a summer evening, where the words themselves seem to take on color. The speaker pictures speech as a round circle of blue, like the clear Caribbean sea, set against a clouded sky. As the sun sets, the light changes the green trees and fills the space between the two people with a growing, radiant orange. Sound and sight blur together, so that talking feels like something you can see.
The mood is warm, calm and quietly close. The speaker seems at ease, even grateful, for this friendly exchange at day's end. But the last two lines shift the tone. As the colors fade toward a white sky, the pair speak of mortality. The poem suggests that the ending of the day and the ending of a life belong together, and that facing this honestly can be gentle rather than frightening.
