Template:Seine Grand Orly bus network/font colour/doc

Usage
Every line, whichever the means of transportation (bus, rail, boat, cable, etc), exploits a predefined set colour from this palette on all its communication (maps, timetables, led panels, etc). From late 2019 onwards, state organ Ile-de-France Mobilités (IDFM) operates a normalization of all transport routes in the Ile-de-France region, which includes RATP (as well as SNCF) transport toutes, colors for easy spotting on maps, which in turn all got normalized as well using the very same format. Since, all the bus routes are renumbered to avoid confuse with other bus routes from other networks.
