Silhouette - Free stock photo

It is a silhouette of trees and a blue, empty stock photo. It is a photograph taken at the time zone that the sun sets in about the evening. It seems to transmit quiet air. The sky is still blue though the shine has not hit trees any longer and it darkens. It darkens gradually after this, and it changes into the color that the sky is near the black. The color where the color is very beautiful, and it settles down the mind is done to the clear sky.
