A warning sign blends into the wall colour. What is the most appropriate improvement?

Answer and explanation

Correct answer: Use a contrasting colour and a clear border

The governing concept is visibility through contrast. A warning sign must stand out from its background so that people can notice and understand it quickly. Using a contrasting colour and a clear border separates the sign visually from the wall, making option A correct. Making it smaller reduces visibility, removing text can remove useful information, and placing it on the floor may make it easy to miss.
