Why is bright yellow often used in a warning sign?

Answer and explanation

Correct answer: It attracts attention quickly

The governing concept is visual salience in visual communication. Bright yellow usually contrasts strongly with its surroundings and is noticeable from a distance, so it helps a warning sign attract attention quickly. Therefore, option A is correct. Colour supports the message but does not replace reading it, so B is too absolute. C contradicts the purpose of a warning sign, while D ignores its communication function.
