The color that illuminates to display a warning for the Digital Control System on the BEAR Power Unit is yellow. This choice is significant because in many systems, including control systems and aviation, yellow is commonly used to indicate caution or a warning that requires attention but does not signify an immediate danger.

By using yellow to signal warnings, operators can quickly discern the level of urgency needed to address the situation, allowing them to take appropriate measures without causing unnecessary alarm. This helps in maintaining safe operations while also providing clear visual communication regarding system status.

While other colors, like red, typically indicate critical failures or immediate dangers demanding instant action, and green usually signifies normal operation, yellow serves a specific role in alerting operators to potential issues that could develop into more serious problems if not monitored carefully. Thus, the use of yellow for warning in the Digital Control System is an important aspect of safety protocols in managing power units.
