Frequently Asked Questions
Name, History & Etymology
History
The color 'International Orange' is most famously associated with the Golden Gate Bridge in San Francisco. When the bridge was being designed in the 1930s, the consulting architect, Irving Morrow, rejected the more common choices of gray or black. He noticed the reddish-orange primer that had been applied to the steel and found it complemented the natural surroundings and made the bridge visible in the fog. He then convinced the engineers and the U.S. Navy (who wanted black and yellow stripes for visibility) to adopt this specific shade. The color is not a single standardized hue across all applications globally, but rather a family of similar vibrant orange-reds. NASA also uses a version of International Orange for its astronaut suits and some components of the Space Shuttle and Ares rockets, again for high visibility and safety.
First Recorded Use
The term 'International Orange' gained prominence with its selection for the Golden Gate Bridge in the 1930s, though similar high-visibility oranges were in use prior.
Cultural Associations
Beyond its practical applications, International Orange has become an iconic color, particularly in the San Francisco Bay Area, where it is synonymous with the Golden Gate Bridge. It evokes feelings of grandeur, engineering marvel, and a connection to the natural landscape. Its use by NASA also links it to exploration, innovation, and safety in extreme environments. It's a color that signifies both visibility and distinction.
