Colours are important factors when we make mental maps. In Stockholm, there are three colours on the subway lines and people often say things like ” I live on the green line”. There are even songs about the different lines.
When the ruling parties in Sweden presented its new subway investment with nine new stations, there was also a big change that ended up slightly overshadowed. The Green Line to Hagsätra, which was completed in 1960, will change the routing in Gullmarsplan – and renamed the Blue Line.
People are concerned.
But one guy, Sebastian, has a different perspective :
Colours on subway lines are generally unpleasant for us who are colour blind. It’s no fun taking the ”green line” when you can not distinguish red from green. It would be better with a checkered line, for example.
