What I am looking for is an impression and not so much a fact, and while I tried to google it, I didn't find what I was looking for.
What colour do the tiles in a tube station generally have, between the entry and the platform? I don't want to know what they look like in a particular station, just what colour someone would first think of who has used it for years. I would also like to know if the light affects the colour somehow.
Thanks in advance.
