Which color should be used by Heads of Administration for correspondence editing?

Heads of Administration typically use purple for correspondence editing as it is designated for this specific purpose within Marine Corps guidelines. This color choice helps to standardize the editing process within communications, allowing individuals to clearly identify changes, comments, and corrections that pertain specifically to administrative correspondence. By using purple, it distinguishes the editing marks from other annotations, such as those made in red for urgent corrections or blue for routine correspondence, ensuring that everyone involved in the communication process can easily follow the edits and revisions made by the Heads of Administration. This practice promotes clarity and organization within documentation, which is critical in a military environment where precision and accuracy in communications are vital.
