Blue pencil

"Blue pencil" refers to the legal practice of editing or amending a document, such as a contract, by physically marking or highlighting sections for change—traditionally with a blue pencil or ink. In a broader context, it symbolizes the act of reviewing, revising, or editing to improve clarity, accuracy, or fairness. The term originated from manual editing practices but now often describes the process of making adjustments in legal, literary, or document review settings, highlighting the importance of careful, deliberate modifications before finalizing a document.
