The Fencing in of Rainbows

It’s no good, don’t even try
to corral a prismatic sky.
It’s an illusion, there are too
many holes, and the blue
is strong enough to bend
before you can try to mend
the chain link fence. The yellow
is too radiant to mellow
and the red so hot
it could meld you to the spot.
Let the rainbow be,
allow it to be free,
to coruscate and bend—
you’ll never find its end.
