The leaves streamed down, trembling in the sun.

They were not green, only a few, scattered through the torrent, stood out in single drops of green so bright and pure that it hurt the eyes; the rest were not a color, but a light, the substance of fire on metal, living sparks without edges.

~Ayn Rand

A shaft of sunlight on a well timed evening dogwalk but it's not easy being green you know ;-)
