Template:Bièvre 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.
 * Bièvre bus network, exploits a set colour palette since around 2020s for its public communication, which mainly includes line colors.
 * This template returns the RGB hexadecimal code for the colour of each bus route on the Bièvre bus network in the Bièvre (indicated by parameter).
 * You can use as a parameter the number/code/name of any Bièvre bus route (e.g.: 401, 402, 408, 412).
