* These are the colors used for rendering signs on this website, and are suitable for most electronic display purposes. Official color values and links to CIE coordinate values can be found on the FHWA MUTCD website (see link below).
** In the past, the Manual of Traffic Signs website used #FFFF00 for yellow. This is a fully acceptable shade for yellow, but the webpage and graphics are moving toward the use of #FFCC00 to slightly better match the shade of most common yellow retroreflective sheetings.
