First shadows appear against the sky.
Before everything was the same shade of dark.
The shadows are just the trees,
And soon enough they are easier to see than the stars.

Then color slowly bleeds into the world.
The sky turns first to a deep dark blue or maybe purple.
The as the light grows, the trees and world gains color too.
Bit by bit, over hours, the world gets slowly more colorful.

Until finally, the big finale.
The sun rises up over the horizon
Shooting the clouds through with color
And fully illuminating the world.
