What sign has Black letters, yellow background?

• A. Location
• B. Mandatory
• C. Warning
• D. Direction

Answer: (D)

The main idea here is how color and contrast signal what kind of information a sign is giving. A yellow background with black letters is chosen for high visibility and to draw attention to information that directs your movement. In an airport or terminal, signs designed to guide you along a route—toward gates, exits, concourses, or taxiways—often use dark letters on a bright yellow field so you can read them quickly at a distance. So this color-and-text combination is best associated with directing you where to go, which is why it’s the correct choice for indicating direction. Other sign types use different color schemes (for example, signs that identify locations or facilities or that enforce mandatory actions or warn of hazards), so they wouldn’t be described by black letters on a yellow background in the same way.
