Green Flag

What is a green flag?

A sign of approval

A green flag is a sign that indicates a good trait about someone or something. It is the opposite of the more common red flag term used to warn about concerning traits in people, jobs, houses, vehicles, financial plans, etc.

The term comes from the use of actual green-colored flags to tell people that they have permission to proceed, like when beginning a race. Green flag was coined to describe positive qualities in potential partners in relationships, such as kindness, loyalty, patience, supportive, and a good sense of humor.
