Warning indicators use color to convey urgency. An amber warning strobe signals a condition that requires attention and could become hazardous if not addressed. It prompts you to pause, verify equipment or procedures, and take corrective action. Red indicates immediate danger or a alarms condition, green shows a safe or normal state, and blue is often used for mandatory actions or informational signals in some systems. Therefore, the warning color is amber.
