He didn't. Neither do most people. Before 1939, there were no rules for school transportation in the United States. None at all. Children got to school however their district could manage -- proper buses, trucks, and in at least one Kansas school district, horse-drawn wagons. The vehicles came in every color imaginable, which meant other drivers on the road had no way of knowing which ones were carrying children. No reason to slow down. No reason to be careful.

He hung fifty paint swatches on the wall of the conference room. They spent days debating which color was safest. They chose a specific yellow-orange that sits in one of the easiest parts of the color spectrum for human eyes to notice. Even in rain, fog, or the dim light of early morning, eyes pick it up faster than most other colors. Combined with black lettering that creates extremely high contrast, the result was a vehicle readable from a long distance under almost any conditions.
