What colour is International orange?
International orange is a vivid, reddish-orange colour, deeper and more red than safety orange. It is designed to make objects highly visible against natural backgrounds, especially in situations where safety or quick identification is important. This colour stands out in fog, at sea, and in the sky, which sets it apart from other oranges and reds that might blend in more easily.
Where does International orange come from?
The name 'international orange' comes from its use in global safety and engineering standards. It was standardised in the United States in 1956 as Federal Standard 595 colour #FS 12197. The colour became widely used in aerospace, engineering, and maritime fields, where clear visibility can be a matter of safety.
How International orange is defined
International orange is defined by standards rather than a single recipe. The exact shade may vary slightly depending on its use: the Golden Gate Bridge uses a specially formulated version to resist rust and moisture, while aerospace and engineering applications follow the Federal Standard 595. The paint is chosen for durability and visibility rather than for its ingredients.

Where International orange is used
This colour is seen on NASA astronaut suits, the Bell X-1 aircraft, and the Golden Gate Bridge. It marks tall towers for air safety, appears on maritime safety equipment, and is used in some sports and trucking. The 25 de Abril Bridge in Lisbon also uses it. Its main purpose is to make structures and equipment easy to spot in challenging conditions.
What International orange means
International orange does not carry symbolic meanings like mourning or luck. Its main purpose is practical: to ensure visibility and safety in engineering, aerospace, and maritime contexts. The colour is chosen for how well it stands out, rather than for cultural or emotional reasons.
