School bus yellow

In April 1939, Frank W. Cyr, a professor at Teachers College, Columbia University, in New York, organized a conference that established 44 uniform national design, construction, and safety standards for school buses in America, including the exterior body color. and because it was conspicuous at a distance and unusual enough to become associated with school buses and groups of children in a route. Cyr became known as the "Father of the Yellow School Bus.") from the Rockefeller Foundation. The yellow-orange color, in three slight variants to allow for different paint formulations, was adopted by the National Bureau of Standards (now the National Institute of Standards and Technology) as Federal Standard No. 595a, Color 13432. ==Outside North America==

North American-style yellow school buses are being introduced in some parts of the United Kingdom, prompted by corporate links to the American industry, for example First Student UK, or a desire to re-brand school buses, such as West Yorkshire Metro's Mybus. ==Examples==
