Ramping Up to Red and Green

I took these photos a few weeks ago when I was wandering around Snug Harbor on Staten Island's north shore. I posted one I took from the top of the ramp leading down to a disused and broken landing dock and pathway along the Kill.

It was only later that I noticed that the couple shots I have looking up the ramp were timed to catch a green light and a red light on Richmond Terrace. Green in sunlight, red in shadow.
