The Carris fleet of trams has traditionally been painted in yellow and white but advertizing liveries make any plain yellow and white vehicles a rarity. The new articulated trams are, for example, all totally covered by advertising liveries which in most cases also cover the windows. Since the inception of the new Carris logo in 1998, however, some of the advertising liveries have been adapted to incorporate the two-rings logo. Buses are now being painted yellow and green, having been orange and mushroom coloured for some years. That livery replaced a dark green livery prevalent into the mid-1970s.
Tickets There is a bewildering array of tickets and passes available to the traveller in Lisbon.
In May 2000 the seven-day version cost 2490 escudos, the equivalent of less than 8 sterling. The four-day version costs Esc.1760. A big advantage of such a pass is that it not only allows freedom of the bus and tram network, the funiculars and elevator, but also the Metro. Apart from the cost-saving, these tickets also avoid the need to join the often lengthy queues for Metro tickets. The Coroa is a zone, of which there are four.
