The ocean vast
 closes in.

Clouds drop.

If the horizon still exists,
 it's behind an approaching
  wall of gray. 

Whatever is closing down
 the world has also
  drained it of color.

The shadows are black.
 The sea foam is white.

Everything else is
 some dim, earthy tone.
  
The sea may have retained
 a hint of green or blue,
  but it's hard to tell --
  so darkened & 
  gray-infused 
  are the waters.

I fear the world may shrink
 to a dot, like an old timey TV
  snapped off, a dot that's
  bright white but cold.
