I have been asked this question about 15 years ago in a pub quiz. We answered green and it was wrong. Unfortunately I don't remember what the answer was. It's difficult to answer this question now that phone booths are redundant because of mobile phones. I asked someone who has worked in France recently and they replied "The only ones I've seen are made of glass. In the good old days they were yellow. I think." Yellow sounds good because as a public service they need to be visible (the reason New York taxis are yellow) but because of the sheer lack of information I'm wondering if there was a standard color at all.
We would still be using telephone boxes and house phones.
France does not have telephone area codes. However, numbers starting with a 1 (or 01 domestically) are normally in Paris.
