The observation that the colors were meant to be absorbed over time rather than explicitly set out reminds me of the old NYC Metro mosaics. https://www.untappedcities.com/secret-meaning-behind-colors-...

While no one would ever navigate by learning what the mosaics mean, it's a fantastic setup for the expected audience of commuters. Give it a month and your brain would associate a given color with your stop coming up soon, and make navigation easier.

I remember having read a story about some wild dogs in Moscow apparently having learned to use the subway and establishing their own "commute schedule".

I always wondered how the dogs would identify the station to leave the train - counting stations or understanding how the announcements worked felt too "smart". But I imagine the simplest way for them would be to just learn the design of different stations over time and jump off once they see a familiar design through the windows.

If I had to make I guess, I'd go with the dogs recognizing the smell. Dogs apparently don't have terribly good vision, but as I'm sure we all know, a very good sense of smell.

Goid point, but from inside the train?

Maybe when the doors open the characteristic smell of that station enters the cars?

dogs, the smart ones, have fantastic memories, a perfect sense of direction, and a basic faith in thereown abilities. that feral dogs, though must be very social with humans, have learned the subway is out on the edge, it's not that far, my moms airidales would go walkabout, shoulder to shoulder, and just sit outside doors they wanted to go through, places they had zero business to be, and be let in, and later out again, got used to bieng driven home by various volenteers and the police, never taken to the pound. taught two dogs to hitch hike, by raising a paw, people would stop, let me in as an afterthought......in the back, dog up front.
