Guide signs usually use________ letter ing on a_______background.

• A. Black lettering on a white background
• B. White lettering on a colored background
• C. White lettering on a black background
• D. Yellow lettering on a blue background

Answer: (B)

Guide signs are designed for quick, easy readability, so they use white lettering on a colored background. The white text contrasts strongly with the background, making route and destination information stand out at a glance. The background color helps drivers quickly recognize the type of information, with green commonly used for directional and destination signs (and blue for services, among others). That’s why white lettering on a colored backdrop is the standard for guide signs. The other color-letter combinations are associated with different sign categories and aren’t the typical look for guide signs.
