What color is typically associated with restricted access visitor passes?

The color red is typically associated with restricted access visitor passes because it signifies that entry is limited to authorized personnel only. This color serves as a clear visual alert that individuals wearing red passes must adhere to specific protocols and guidelines while in restricted areas. The use of red in this context is universally understood to indicate caution and the need for heightened awareness, ensuring that access is managed appropriately for security reasons.

In environments such as military bases, government facilities, or other areas requiring controlled access, the red color helps security personnel quickly identify individuals who may not have clearance, thus maintaining the integrity and safety of those areas. This practice aligns with standard visual communication protocols where red is universally recognized as a color denoting severity or limitations on access.
