History

The color 'School Bus Yellow' was officially adopted in 1939 at a conference in New York, organized by Dr. Frank W. Cyr, a professor at Teachers College, Columbia University. The conference brought together educators, transportation officials, and paint experts to standardize school bus construction and safety. The specific shade of yellow-orange was chosen because it is more easily noticed in the peripheral vision than other colors, and it is also highly visible in the dim light of early morning and late afternoon. The color was originally called 'National School Bus Chrome' but is now more commonly known as 'School Bus Yellow' or 'School Bus Glossy Yellow'.
