A sign distinguishes two conditions using colour alone. For which user may this design be especially difficult?

Answer and explanation

Correct answer: A person with colour vision deficiency

The governing concept is accessibility in visual communication. A colour-only signal can be difficult for a person with colour vision deficiency because some colours may not be distinguishable. Thus option B is correct. Reading speed, height, and handedness do not normally affect the ability to interpret a colour-coded sign; adding text, symbols, or patterns would make it more inclusive.
