MAX: How ya doing?
LORELAI: Mm, I’m stable.
MAX: You’re a lovely shade of puce.
LORELAI: Don’t say puce. It sounds too much like another word I don’t wanna hear right now.
Puce is a dark red or purple-ish brown colour. The word comes from the French word for “flea”, and is supposedly named for the colour of bloodstains on bed sheets after a flea has been crushed.
Lorelai moans that the colour reminds her of the word “puke”.
