The Golden Gate Bridge has always been painted orange vermilion, deemed "International Orange." Rejecting carbon black and steel gray, Consulting Architect Irving Morrow selected the distinctive orange color because it blends well with the span's natural setting as it is a warm color consistent with the warm colors of the land masses in the setting as distinct from the cool colors of the sky and sea. It also provides enhanced visibility for passing ships. If the U.S. Navy had its way, the Bridge might have been painted black and yellow stripes to assure even greater visibility for passing ships.
