The pop colour experiment was not lasting long. In 1974, the DB decided for ivory/ocean blue instead. The new livery of 1986 had some similarity to the pop colours of the early 1970s though; now the colours stood for the train categories. From 1996 on, only EC/IC and NachtZug (night train) cars were painted with a window band (in traffic red), and since 2001, only those of NachtZug.
A list of all numbers of the coaches with Pop livery can be found here.
Vermillion was chosen to be eye-catching enough for first class and
first/second class cars. Some of these cars were delivered new in
pop colours. The prototype ABwümz 227 was of unpainted stainless steel
with vermillion window band.
For a long time, purple red had been the colour of the Mitropa and DSG
for sleeping and dining cars. It was used for several dining cars
(mostly of the pre-war type WRüge 152), sleeping and buffet cars.
For couchette cars, no agreement could be found; the colours cobalt
blue, blue lilac and red violet were used.
A cobalt blue window band was used as the livery for a whole train
as well as the livery for 2nd class cars. As the compartment cars
Büm 234 were just being delivered at that time, a whole series of
these cars were painted in cobalt blue/pebble grey in factory. Before,
cobalt blue had been the colour of fast electric locomotives and first
class cars. The prototype Bwümz 237 was of unpainted stainless steel
with cobalt blue window band.
A short train was painted with a chrome green window band. Afterwards,
this colour was used for several luggage cars Dm 902. Before, chrome
green had been the colour of slower electric locomotives and many
coaches of various types.
The urban EMUs class 420/421 were originally presented in three different liveries, also in the arrangement of the pop colours. The variant with a window band in pure orange (RAL 2004) became the new standard for AC S-Bahn trains until the 1980s, and was also used for the "x" cars for locomotive hauled S-Bahn trains, as well as for a number of electric locomotives class 111. The variant with a window band in purple red (RAL 3004) was meant to be used in Frankfurt, however only one train was painted like that. For München, the first series of class 420/421 were painted with a window band in green blue (RAL 5001), which was later replaced by orange, however still a few trains are operating with the original blue window band.
