Two older companies, one régie and the colours of Paris.

RATP is the public transport operator of Paris and its region, and its name still carries the form it was given at the start. English Wikipedia describes the RATP Group as a French state-owned enterprise headquartered in Paris that originally operated under the name Régie autonome des transports parisiens. It says the RATP was created on 1 January 1949 by combining the assets of the Compagnie du chemin de fer métropolitain de Paris (CMP), which operated the Paris Métro, and the Société des transports en commun de la région parisienne (STCRP), which operated the city’s buses.

The operator runs several modes under one name. English Wikipedia lists the Paris Métro, the Île-de-France tram lines, the RATP bus network and part of the regional express rail network, the RER.

The visual identity has moved through several marks. French Wikipedia, in the identity section of its article on the RATP, says that in 1951 the company, heir to two former transport companies and operating within Paris, adopted the colours of the city, red and blue. It says the logo was modernised in 1960, still in red and blue, and that in 1976, with the arrival of the RER, the logo took on a slanted typography.

That 1976 mark has had a second life as merchandise. Time Out Paris, in a report by Rémi Morvan on 4 March 2022, said the RATP had launched a line of clothing and accessories in 2019, for its seventieth anniversary, printed with former slogans and logos. It said two new pieces, inspired by the work clothes of the company’s staff, were screen-printed with the RATP logo used from 1976 to 1992.

A river, a ring road and a face looking up.

The current logo dates from 1992. French Wikipedia says it represents the Seine schematically as a stylised face inside a jade-green circle, which it calls the RATP’s reference colour, symbolising the Île-de-France region. English Wikipedia describes the same mark as the meandering path of the Seine through the Paris region stylised as the face of a person looking up.

Outside readers have parsed it the same way. The transit consultant Jarrett Walker, writing on his blog Human Transit on 10 July 2010, described the logo as a circle with a curving blue line through it that reads as the city and its river, with liberties taken in the river’s shape to suggest a human profile whose face seems to look upward. He noted that the RATP website at the time paired the mark with the slogan “Aimer la ville”, love the city.

The mark arrived with a family of smaller signs. The transport-design blog The Beauty of Transport, in a post on 18 October 2017, said that new circular logos for the RATP’s various transport modes were introduced in 1992, all using the rounded lettering of the RER. It said the mode logos kept that rounded type after station names moved to a new face.

The same post sets out why the Métro’s signs looked mixed before then. It says platform name signs were long made in tiles, generally white text on a blue background, in styles that depended on whether a station had been built by the CMP or by the Nord-Sud company. When the initial RER lines were built in the 1970s, it says, their signs returned to white on blue, set in Univers, and the RATP asked Univers’ designer Adrian Frutiger to draw a special all-capital version for the Métro, which was used only to replace damaged or out-of-date signs. A rounded RER alphabet followed, and in the 1980s, it says, Neue Helvetica brought upper and lower case to bus and Métro signs.

Jade green, Seine blue and a narrow sans.

A city transit system is read in fragments: a glance at a map on a platform wall, a coloured stripe above a door, a letter on a post at the top of a staircase. The diagram map often becomes the brand itself. It straightens curves, evens out distances and turns a tangle of tunnels into a few clean lines, and people come to picture their city in that shape. Line colours then work as a public language. Once a line is red or green on the map, the same colour appears on platform walls, on direction signs and in the way people give directions, so a change of colour has to be carried through every sign, timetable and leaflet at once. Station names are the vocabulary of that language, and their lettering has to be legible from a moving carriage, in poor light and at a slant, which favours plain letterforms, generous spacing and strong contrast between text and background.

Above ground, the system has to announce itself among shop signs and traffic lights. Many networks rely on a single letter or a simple shape set on a post or a box at each entrance, lit at night and repeated so often that it reads as a symbol before anyone takes in the word. Below ground, some operators bring in artists so that each station has a character of its own, which also helps passengers recognise where they are. The smallest pieces carry the identity too: a ticket, a travel card or a validator has to show the same colours and marks at a scale that fits in a hand.

A house typeface from 1996 and entrances from 1900.

The RATP’s typeface is Parisine. French Wikipedia says it was created for the RATP by Jean-François Porchez of Porchez Typofonderie and has been used since 1996 in the Métro, the RATP-run parts of the RER, the trams and the buses. It places its adoption inside “Autrement Bus”, an early-1990s programme to unify the signs of the different modes, which also brought blue as the base colour and a colour code for the lines. It says Parisine replaced Neue Helvetica and was meant to be readable from a distance, including by visitors whose native script is not Latin, and to be narrower, at 90 percent of the width, and more even in width than its predecessor. English Wikipedia says the original cuts were a Bold and Bold Italic based on the proportions of Helvetica Bold, that the family was extended in 1999 for communication material and maps, and that Parisine Office followed in 2005 to replace Gill Sans.

The Beauty of Transport dates the face differently, saying Parisine was introduced in 1997. It says the construction of Métro line 14 in the 1990s, with its need for all-new signs, led the RATP to commission Porchez, and it points to a looped g and narrow letters that fit long station names. It adds that the RATP commissioned Parisine Girouette in 2013 for LED destination displays on buses. French Wikipedia says a separate typeface, Grand Paris Express, was introduced in 2024 at the Aéroport d’Orly station for the new lines 15 to 18.

The Métro’s entrances of 1900 predate the RATP. English Wikipedia says Hector Guimard designed the original entrances between 1900 and 1913 for the CMP, in cast iron and glass, with standard parts, railings carrying the letter M and signs in his own lettering reading “Métropolitain” or “Métro”. It says 141 entrances were produced, that 86 survive as protected historical monuments. For a renovation that began in 1999, it says, the RATP restored them in two greens, vert wagon at leafy sites and the slightly bluer vert allemand at fully urban ones. It says the RATP has also presented Guimard entrances, mostly replicas, to systems and museums abroad, including a genuine one at Montreal’s Square-Victoria station, installed in 1967.

For a design guide, RATP shows how an operator can layer a 1900 entrance, a 1992 logo drawn from the city’s own river and a typeface cut for long station names, and keep each in use. Compare SNCF, the French national railway that shares stations and RER lines with the RATP, and London Underground, whose Johnston lettering Parisine is often set against. For this guide we use jade green, Seine blue and Guimard green with a sans, an unofficial interpretation; no product or logo is reproduced.
