In the standard sequence of colors used for emergency exit lettering, which color appears third?

• A. Red
• B. Black
• C. White
• D. Yellow

Answer: (D)

Color signaling in emergency exit lettering follows a careful order designed to maximize quick recognition in stressful situations. The third color in that standard sequence is Yellow because it provides a bright, attention‑grabbing cue that helps people spot the exit even when visibility is reduced, without conveying the immediate danger that red signals. White is typically used for the letters or symbols to ensure legibility against backgrounds, while red is used to indicate danger or prohibition. Yellow sits after these elements to draw the eye to the exit path as a clear, high-contrast sign component.
