Cobalt Blue

 
As he walked,
        he thought of cobalt blue,
 
And the many acquaintences
        who knew it by name
 
And admired or even
        loved it.
 
He thought about their isolation
        in this affection,
 
Their membership in a group
        that never meets,
 
Diffuse and unknown
        even to their own selves,
 
Secretly united only by
        joy of observation,
 
Who regale it
        in their vases and walls,
 
In the folds of curtains,
        feathers of a forgotten bird,
 
At dusk the edges
        of distant mountains.
 
Some are illuminati who know
        the truth of the hue,
 
That, absent cobalt blue,
        only vacuum would exist,
 
With occasional photons
        or other-ons
 
Racing from each other
        at the speed of light
 
In the slow entropic-death
        of a cobalt-blueless universe.
 
He realized the planter beneath
        the garden wall
 
Asserts his existence,
        that all is here and real,
 
That he can stop holding his breath
        and breathe once again,
 
That the race is slow,
        and oblivion infinitely distant.
 
                — Cobalt blue is both a color and a substance
                (cobalt aluminum oxide — CoAl2O4). The
                nature of our universe predicates the existence
                of cobalt, aluminum, and oxygen.
