I am a million shades of grey

The day I became earthling
Rainbow rejected my name.
Stubble, stalk and hay
nourish me all day.

Where fear sends, I go
What hurt feeds, I swallow
Call me King of abysmal lows
Bet you already know.

Why are my bones visible?
I had a beef with sinews.
Why am I uncolourful?
I'm black...it's no news.

But...

There's peace within
flowing effortlessly like streams...

Who altered my reflection?
The mirror?
Your tongues?
God?
gods?
My fancy Biro?

Who can paint the smile in me
on the surface of my face?
Who can reach deep in my soul
and unearth my inner glow?

Who?
Me!
Yes... I alone can paint the smile in me
