> Personally, I found this the most beautiful color scheme.

To my eye, in these colors the PCC looks like it's Eastern European spin-off, a Tatra from the Eastern Bloc. The weed within the right-of-way shares the same opinion )) Sorry for a bit of humor ) As always, PCC is a beauty, in any colors...

Until the 1980s, some European countries (Belgium, France, Germany...) and quite a few cities still used the historic factory colours. Almost everywhere at the same time, including Antwerp, people started thinking about other colours.

In Antwerp, an experiment with a green tram took place: this is the only colour still missing here, but I promise to post it in this gallery soon.
https://transphoto.org/articles/6922/ The photos are in my collection, but I don't know if I've them all: many (between 4 and 6) variants were tested.

Despite frantic attempts to warm up the public with the green colours, no one was enthusiastic.
As mentioned: the same thing happened in a lot of other cities and in Germany (e.g.: Ruhr area, Köln...) the red colour was introduced.

Where exactly the inspiration came from: only the creator knows this.

For me, the colour scheme looked very familiar: not Tatras at all (different kind of red and cream at the top) but Vienna!

Coincidence? No one knows the official version, if there ever was one. The fact is that the red colour appealed to everyone and was applied immediately.
