Envy is often associated with the colour green, as in "green with envy". The phrase "green-eyed monster" refers to an individual whose current actions appear motivated by envy.
Envy is generally considered an unpleasant emotion to feel, as well as being responsible for unpleasant behaviour towards others. Historically it has been listed as one of the seven deadly sins.
A religious term for envy is covetousness, which is forbidden by the Ten Commandments in the Bible.
