into the blue-green fog
From the novel Monopole.
Once the stranger goes on his way, Teddy steps from the flow of the crowd rushing in and out of the station, and stands looking up at the behemoth glass structure. He sees the blue-green sky through the upper portion of the glass rising above him. His sight drops slowly down the transparent form, which becomes foggier as his gaze falls to the pedestrians rushing to and from the curvilinear metallic train cars that come and go every few seconds. The train cars arrive and depart silently but cause great commotion. Each receding train car disappears into the blue-green fog, like a big metallic dream evaporating in the first few moments after waking. Teddy’s view beyond the glass shallows, finding his own faint image staring back.
