Green Light

"Green Light" often refers to permission or approval to proceed with an action, originating from traffic signals where green indicates it’s safe to go. In a broader context, it symbolizes authorization or confirmation to start or continue a project, decision, or plan. For example, a manager giving the "green light" to a new initiative means approval has been granted, allowing the team to move forward. It’s a straightforward, universally understood metaphor for positive confirmation that necessary conditions are met, and it’s safe to proceed.
