How am I to define you?

a poem by Sindhu Sreekumar

The greens form irregular
patterns over the road…
The bright yellow illuminations
break all frontiers,
fade the impressions
of the greens.
Somewhere between
the appearance and the disappearance
the impressions slide
into an apparent invisibility.
Reduced to an awkward gray
they skulk in corners.
Suddenly they shoot up,
then it simply disappears
or does it?
My impressions breathe in
the illuminations and die in it.
Fading and appearing,
Never disappearing
How am I to define you?
