Stop buttons are which color?

Stop buttons are which color?

• A. Blue
• B. Green
• C. Yellow
• D. Red

Answer: (D)

Stop buttons are red because red signals urgent action to halt due to danger or an emergency. This color coding is part of safety standards for control panels, where red is reserved for stopping or emergency stop devices, often designed to be large and easy to press. Green is used for go or normal operation, yellow for caution, and blue for mandatory actions or information, so those colors don’t convey the same immediate halt message as red.
