by ad infinitum
[o]I've got a hypothetical which I hope I don't have to face in-game anytime soon. Here goes:
Let's say C0da is yellow and the blue city Chicago has become faded and has a panic level 4. When entering Chicago, which color card must be discarded by panic level rules? The city's original color, blue, even though the city has become faded? Yellow, because that's the C0da color? I don't see this addressed specifically in the rules, and I could see a reasonable argument either way.
