What color is typically used to indicate urgency in classified items documentation?

The color red is commonly used to signify urgency in classified items documentation. This association highlights the critical nature of certain items that require immediate attention or action. In many contexts, including military and governmental operations, red serves as a visual cue to alert personnel to the importance and urgency of the information or materials being handled. This convention helps maintain adherence to protocols and ensures that sensitive information is managed appropriately. Using a bright, attention-grabbing color like red effectively communicates the need for cautious handling, swift decision-making, or heightened security measures. In contrast, other colors like yellow, green, and blue are generally linked to different categories or levels of information, but do not convey the same immediate sense of urgency as red does.
