Blue pencilling is a term that refers to editing or censoring written material. The opposite of blue pencilling can be expressed in several words or phrases, including inclusion, addition or expansion of text. Rather than removing words or ideas, writers may choose to build upon them or add nuance to their writing. A related term is "redlining," which refers to technical revisions or corrections made to writing, while "greenlighting" or "approving" refers to accepting or allowing written material without changes or revisions. In business or legal contexts, "blacklining" refers to text that indicates changes made to a previous version. In any case, these antonyms stand out as the antitheses to blue pencilling, which to many, can seem stifling or limiting.
