Blue safety color represents information such as signs and bulletin boards.

• A. Orange
• B. Blue
• C. Red
• D. Green

Answer: (B)

In safety color coding, blue is used to convey information rather than a hazard. That means blue signs and markings are there to point you to notices, instructions, or locations for information—like posters, bulletin boards, or manuals—rather than warn you about danger. This helps people quickly distinguish informational messages from warnings or emergency cues.

For contrast, other colors indicate different things: orange highlights hazardous machinery or surfaces, red marks fire safety or emergency equipment, and green shows safe conditions or safety equipment locations. So blue stands out as the go-to color for informational postings.
