Black.

                                                        The colour of the nights sky - I am. 
The colour centred in your eye - I am. 

I hide in crevices and corners alike, 
Until the sun falls, when I become night. 
I cannot be defined as one, 
Within the beholder, I truly become, 
Grey can be a close substitution, 
But I am the colour of pure pollution, 
I am darker than the clouds before rain, 
For I am associated with darkness and pain, 
I am liquid lava, when heat becomes cool, 
Hardened and darkened, as a changed molecule, 

I never die, even within sunlight I lie. 

I cannot be defined as albino, because I am the colour negro.
