Why is red used in warning signs?

Answer and explanation

Correct answer: It attracts attention quickly

The governing concept is visual communication through colour emphasis. Red is a strong, conspicuous colour that is commonly used to signal danger, stopping, urgency, or caution, so it helps people notice a warning quickly. Therefore, option A is correct. Calm and relaxing effects are more often associated with some blues or greens; blending into the background and reducing visibility would defeat the purpose of a warning sign.
