Darkest of Nights

There is a color that almost imperceptible in the night sky.It is more blue than black, more violet than blue.Clear skies make it have a deep pile carpet-like feel.Hazy nights have a vapor that lingers, celestials steadfastly riding amid the mist.
As easy as it might seem I am not able to easily reproduce this color in paintings, I can get close, but the luminous clarity is always just an edge away. The natural world is bewildering.
