According to a New York Times article (http://www.nytimes.com/1992/06/17/us/cooling-and-safety-trend-for-buses-white-tops.html), bus tops are painted white to help cool the interior temperature. "Painting the bus tops white dropped the interior temperature an average of 10 degrees during the summer, with as much as a 17-degree difference at peak hours. Wintertime temperatures were lower by only 3 to 4 degrees. The study also found that children behaved better on buses in cooler temperatures ..."
All school buses are yellow because if they weren't yellow, they wouldn't be very easy to see in the dark. If people couldn't see school buses, then many people would miss the bus. Yellow school buses in the dark are easier to see than dark colored buses would be. If school buses weren't yellow they wouldn't be easy to see in the morning when everything is dark. Since buses are yellow, they catch your attention better than any other color. The main reason school buses are yellow is because safety rules and regulations require school buses to be yellow. The color yellow was picked because the black lettering on a yellow background can be most easily seen against that color.
The roofs of some school buses are white because these buses are air conditioned. The white roof deflects some of the suns warming rays.
