When one is "envious", they are said to be what color?

The story behind the answer

Green is correct because English idioms link envy to the color green—people are often said to be “green with envy.” Shakespeare popularized the image as the “green-eyed monster” (in Othello), blending envy/jealousy with a sickly green hue.

Historically, the association may trace back to humoral theory, where an excess of bile was thought to cause a greenish pallor and uneasy emotions. The color stuck in culture, showing up in literature and everyday speech. To remember: envy and green both start with “G,” and you can picture someone turning slightly green—like seasickness—when they see someone else’s good fortune.
