A Pink Horizon

We know that a red sky [at night]
Portends a clear day [at morning]
What, prithee, does a sky of pink
Foretell? Should we expect our 
Day to show uncertainty rather
Than clarity? Erring [of course]
On the side of delighting sailors?
I tend to think [rather without
Evidence] that the pink is red 
Shivering from the cold, made 
Pale by temperatures too low
For comfort, too high for frost.
Pink sky at dusk, warm up the
Cabin, Captain [and if you must
Sail] wear long Johns and a parka.
