The 5 People Who Get This Will Probably Enjoy It

In Ilium did Homer Khan
A baffling metaphor decree;
Linguistical debate began
In papers measureless by man
About the wine-dark sea.

Beware! Beware!
His violet blood! His chartreuse hair!
Was their language imprecise,
Or were they colorblind instead
If they called honey blue or red
In illustrational device?
