History

The color 'International Orange' was specifically chosen by consulting architect Irving Morrow for the Golden Gate Bridge in San Francisco. He was inspired by the red lead primer that had been painted on the steel during fabrication.

It was preferred over more conventional choices like black or gray. The specific hex code #ba160c is a common representation of this color, though slight variations exist.

First Recorded Use
