What does the 10th Order to the Sentry specify regarding colors and standards?

The 10th Order to the Sentry specifically states that a guard must salute colors and standards when they are in view. This reflects a fundamental respect for the symbols of national and organizational pride, which include flags and other emblems representing the unit or country. Saluting when colors are in view serves not only as a show of respect but also reinforces the values of discipline and honor within the military and cadet training environments.

The other options do not adequately capture the significance of the action specified in the 10th Order. For example, ignoring colors unless directed, only saluting when addressed, or reporting their presence lacks the necessary respect and formal recognition that is required when colors and standards are displayed, undermining the customs and courtesies integral to military protocol.
