apparition

Pink clouds of cherry blossoms levitate
upon a sea in countless shades of green
a challenge for the mind to contemplate
within three pounds of squishy wet machine.
If clouds wax pink, why need a sky be blue?
and must your lexicon comport with mine?
The frequencies reflected set the hue,
but conversation's tinted by each mind.
The qualium evoked when you see "red"
might differ from what I call by that name.
I can't know what goes on inside your head,
'though lazily, I treat the two the same.
A vernal contemplation en pleine air
is pretty, 'though I can't be sure what's there.
