What does a TA warning look like?

• A. Amber circle
• B. Red Square
• C. Blue Triangle
• D. Green Diamond

Answer: (A)

Status indicators use color and shape to communicate quickly. An amber circle signals caution and draws attention without signaling an outright error or alarm. The amber color is chosen because it alerts you to slow down and check, while the circular shape is a clear, simple status marker that many systems use for ongoing states. That combination—amber plus circle—fits a warning best, signaling you should review or acknowledge something without implying a severe failure.

If you saw a red square, that would feel like a more urgent or critical problem. A blue triangle typically means information or guidance, not a warning. A green diamond often marks success or completion. So the amber circle is the most appropriate symbol for a warning.
