International orange is a color used in the aerospace industry and maritime industry to set objects apart from their surroundings, similar to safety orange, but deeper and with a more reddish tone.

Variations

There are several variants of international orange.

Aerospace

The Advanced Crew Escape Suits pressure suits worn by NASA astronauts and the previous Launch Entry Suit use this color, as opposed to the lighter tone of safety orange used by the United States Air Force's high-altitude suits. This was also planned for the Constellation Space Suit systems that were to be flight-ready by 2015.

Golden Gate Bridge

|title=International Orange (Golden Gate Bridge) |hex=F04A00 |isccname=Vivid reddish orange}} The tone of international orange used to paint the Golden Gate Bridge in San Francisco, California is slightly lighter than the standard International orange used by military contractors and in engineering, thus increasing its visibility to ships, but darker than the one used in aerospace. The international orange paint used on the Golden Gate Bridge is specially formulated to protect the bridge from the danger of rust from salt spray off the ocean, and from the moisture of the San Francisco fog that frequently rolls in from the Pacific Ocean through the Golden Gate to San Francisco Bay. The 25 de Abril Bridge in Lisbon, Portugal also uses this color.

Engineering

The adjacent box displays the generic, red tone of international orange used by military contractors and in engineering generally.

The source of this color is Federal Standard 595, a U.S. federal government standard set up in 1956 for paint colors which is mostly used by military contractors and also in engineering. International Orange is designated as Federal Standard 595 color #FS 12197.

In accordance with air safety regulations, some tall towers, e.g. Tokyo Tower and the Yerevan TV Tower, are painted in white and international orange.

Sports

The World Football League used international orange (instead of the traditional white) for the stripes on their footballs. The league also painted a short international orange mark on the field at the two-yard line.

Trucking

Schneider National paints its trucks, tractors, and trailers "international safety orange" (Omaha orange, PMS165).

Maritime

Most Safety of Life at Sea (SOLAS) equipment on board ships and small vessels are colored "international orange".
