Paris has colours, numbers or names (Yellow/1/Chateau de Vincennes-Le

London has colours and names (Green, District).

So, from that point of view, Paris has three options to choose
whichever one you prefer; London has two.


The trouble is that Paris hasn't been consistent with colours. I remember
line 1 as red, 7 as purple, for example.

I've seen maps with the "wrong" colours, but it has always been an
"unofficial" version (to avoid paying copyright I presumed).

I've never seen "wrong" colours on a current RATP map.
