APPENDIX B
NATIONAL SCHOOL BUS YELLOW


 The color known as National School Bus Yellow was designated as such by the 1939 National Conference on School Bus Standards. The National Bureau of Standards of the United States Department of Commerce assisted in developing this color and its colorimetric specifications, as follows:

 At the 1980 Conference the colors in use were reviewed. A color standard was selected, slightly different from the above, and specific tolerances were chosen. These tolerances will insure a continuity of appearance from school bus to school bus, and within the same school bus when different elements are finished or refinished at different times. Specification for the Standard Color, with light and dark tolerances (Upper and Low Reflectances) are shown below in tabular form.
