What color page designates a Technical Order Page Supplement (TOPS) that supplements rather than replaces a TO page?

• A. Blue
• B. Yellow
• C. White
• D. Green

Answer: (D)

Color coding for Technical Order page supplements shows whether the update adds information or replaces existing content. A green TOPS is used to supplement the page, meaning it provides additional procedures or data without removing or overwriting what’s already there. This helps maintain the original instructions intact while adding new steps or notes, so technicians can reference both the original page and the supplement together. If the change were to replace the page entirely, a different color would be used to indicate that the old content is superseded and should be discarded in favor of the updated page. Green, therefore, best fits the idea of adding information without discarding the original material.
