I came home at dusk a few nights ago; not an unusual occurrence in itself. It must have been the color that drew my eyes to a ridge across the Allegheny River.
The uneven tree line was capped by silver that gradually shaded into a glowing blue. It happens for a short time on summer nights, just at dusk. The color of the sky, even at the furthest reaches from retreating light, retains this glowing blue.
It took me twice as long to walk home that evening. I kept getting lost in that incredible color and light, watching as indigo shaded the southern ridge and silver faded from the northern ridge.
