The Golden Gate Bridge, an iconic landmark, is renowned for its vibrant color. But it’s not red. The official color is International Orange, a shade specifically chosen for its aesthetic and functional properties. This article explores the history and reasoning behind the unique color of the Golden Gate Bridge.
The Golden Gate Bridge’s distinctive International Orange color stands out against the backdrop of San Francisco Bay.
The Origins of International Orange
The story begins with the bridge’s construction. The steel used, fabricated by Bethlehem Steel, was initially coated with a red lead primer for protection against corrosion. Consulting architect Irving F. Morrow, commuting to the construction site by ferry, was captivated by this red lead color. He began extensive color studies, ultimately selecting “International Orange.”
Why International Orange?
Morrow’s decision was multifaceted. He recognized the importance of the bridge’s color in relation to its surroundings. International Orange harmonized with the natural landscape, blending with the surrounding hills while contrasting beautifully against the blues of the sky and ocean. This ensured the bridge remained visually striking in varying weather and light conditions.
The art deco design of the Golden Gate Bridge is further enhanced by its International Orange color.
Furthermore, Morrow believed the color enhanced the bridge’s Art Deco design. The warm hue highlighted the structure’s lines and curves, contributing to its overall elegance.
Distinguishing “International Orange”
It’s crucial to note that the “International Orange” used for the Golden Gate Bridge is unique. While the name existed beforehand, typically used in the aerospace industry for visibility, the bridge’s specific shade was custom formulated. Morrow’s “International Orange” possesses a richer, deeper reddish tone than standard safety orange.
Deliberate Color Selection Process
Morrow meticulously documented his color selection process in his 1935 “Report on Color and Lighting.” He considered various alternatives, including black, gray, and aluminum, but ultimately rejected them. Black was deemed too stark, diminishing the bridge’s scale. Gray lacked visual appeal, while aluminum would make the towers appear insignificant. Even a warm gray, considered a close second, couldn’t rival the vibrancy of International Orange.
The International Orange color plays a crucial role in how the Golden Gate Bridge is illuminated at night.
Color Formula and Modern Application
The precise formula for Golden Gate Bridge International Orange remains consistent, though the paint is procured through competitive bidding. Currently, Sherwin-Williams supplies the paint, custom-mixed to match the original formula. The closest commercially available color is Sherwin-Williams “Fireweed” (SW 6328). For those seeking a more precise match, the CMYK values for Golden Gate Bridge International Orange are: Cyan: 0%, Magenta: 69%, Yellow: 100%, Black: 6%.
Conclusion: A Color That Defines an Icon
International Orange wasn’t a random choice. It was the result of careful consideration, aesthetic vision, and a desire to create a structure that harmonized with its environment while standing as a bold, enduring symbol. The color, as much as the bridge’s design, contributes to the Golden Gate’s global recognition and enduring allure. It’s a testament to the power of color to enhance architecture and create a lasting legacy.
