Night sky

Why!? I'm trying to figure out why, darkness is the colour of the night sky. I mean sure, that must mean the sun has gone by but I'm still trying to figure out.. WHY!

Why not red, or purple or green! Darkness, is NOT a colour - it's a 'shade' it would seem.

The night sky is endless, a concept that is hard to believe - it's about as limitless, as a human dares to dream. 

Dark sky ? < that's the emoji for night time! But who says that's a concept of time where the world has to say goodbye. I love being awake at night - it's currently 00:39 but I'm not sleeping so tight.
